Oklahoma (/ˌoʊkləˈhoʊmə/ (listen); Choctaw: Oklahumma [oklahómma]; Cherokee: ᎣᎧᎳᎰᎹ, Okalahoma [ògàlàhǒːmã́]) is a state in the South Central region of the United States, bordered by Texas on the south and west, Kansas on the north, Missouri on the northeast, Arkansas on the east, New Mexico on the west, and Colorado on the northwest. Partially in the western extreme of the Upland South, it is the 20th-most extensive and the 28th-most populous of the 50 United States. Its residents are known as Oklahomans and its capital and largest city is Oklahoma City.
The state's name is derived from the Choctaw words okla, 'people' and humma, which translates as 'red'. Oklahoma is also known informally by its nickname, "The Sooner State", in reference to the settlers who staked their claims on land before the official opening date of lands in the western Oklahoma Territory or before the Indian Appropriations Act of 1889, which increased European-American settlement in the eastern Indian Territory. Oklahoma Territory and Indian Territory were merged into the State of Oklahoma when it became the 46th state to enter the union on November 16, 1907.
With ancient mountain ranges, prairie, mesas, and eastern forests, most of Oklahoma lies in the Great Plains, Cross Timbers, and the U.S. Interior Highlands, all regions prone to severe weather. Oklahoma is at a confluence of three major American cultural regions. Historically, it served as a government-sanctioned territory for Native Americans removed from east of the Mississippi River, a route for cattle drives from Texas and related regions, and a destination for Southern settlers. There are currently twenty-five Native American languages still spoken in Oklahoma.
A major producer of natural gas, oil, and agricultural products, Oklahoma relies on an economic base of aviation, energy, telecommunications, and biotechnology. Oklahoma City and Tulsa serve as Oklahoma's primary economic anchors, with nearly two-thirds of Oklahomans living within their metropolitan statistical areas.

The name Oklahoma comes from the Choctaw language phrase okla, 'people', and humma, translated as 'red'. Choctaw Nation Chief Allen Wright suggested the name in 1866 during treaty negotiations with the federal government on the use of Indian Territory. He envisioned an all–American Indian state controlled by the United States Superintendent of Indian Affairs. Oklahoma later became the de facto name for Oklahoma Territory, and it was officially approved in 1890, two years after that area was opened to white settlers.
In the Chickasaw language, the state is known as Oklahomma', in Arapaho as bo'oobe' (literally meaning 'red earth'), Pawnee: Uukuhuúwa, and Cayuga: Gahnawiyoˀgeh.

Indigenous peoples were present in what is now Oklahoma by the last ice age. Ancestors of the Wichita and Affiliated Tribes (including Teyas and Escanjaques and Tawakoni), Tonkawa, and Caddo (including Kichai) lived in what is now Oklahoma. Southern Plains villagers lived in the central and west of the state, with a subgroup, the Panhandle culture people, living in the panhandle region. Caddoan Mississippian culture peoples lived in the eastern part of the state. Spiro Mounds, in what is now Spiro, Oklahoma, was a major Mississippian mound complex that flourished between AD 850 and 1450. Plains Apache people settled in the Southern Plains and in Oklahoma between 1300 and 1500.
The Expedition of Spaniard Francisco Vázquez de Coronado traveled through the state in 1541, but French explorers claimed the area in the early 18th century. By the 18th century, Comanche and Kiowa entered the region from the west and Quapaw and Osage peoples moved into what is now eastern Oklahoma. French colonists claimed the region until 1803, when all the French territory west of the Mississippi River was acquired by the United States in the Louisiana Purchase. The territory was a part of the Arkansas Territory from 1819 until 1828.
During the 19th century, the U.S. federal government forcibly removed tens of thousands of Native Americans from their homelands from across North America and transported them to the area including and surrounding present-day Oklahoma. The Choctaw was the first of the Five Civilized Tribes to be removed from the Southeastern United States. The phrase "Trail of Tears" originated from a description of the removal of the Choctaw Nation in 1831, although the term is usually used for the Cherokee removal.
Seventeen thousand Cherokees and 2,000 of their black slaves were deported. The area, already occupied by Osage and Quapaw tribes, was called for the Choctaw Nation until revised Native American and then later American policy redefined the boundaries to include other Native Americans. By 1890, more than 30 Native American nations and tribes had been concentrated on land within Indian Territory or "Indian Country".
All Five Civilized Tribes supported and signed treaties with the Confederate military during the American Civil War. The Cherokee Nation had an internal civil war. Slavery in Indian Territory was not abolished until 1866.
In the period between 1866 and 1899, cattle ranches in Texas strove to meet the demands for food in eastern cities and railroads in Kansas promised to deliver in a timely manner. Cattle trails and cattle ranches developed as cowboys either drove their product north or settled illegally in Indian Territory. In 1881, four of five major cattle trails on the western frontier traveled through Indian Territory.
Increased presence of white settlers in Indian Territory prompted the United States Government to establish the Dawes Act in 1887, which divided the lands of individual tribes into allotments for individual families, encouraging farming and private land ownership among Native Americans but expropriating land to the federal government. In the process, railroad companies took nearly half of Indian-held land within the territory for outside settlers and for purchase.
Major land runs, including the Land Run of 1889, were held for settlers where certain territories were opened to settlement starting at a precise time. Usually land was open to settlers on a first come first served basis. Those who broke the rules by crossing the border into the territory before the official opening time were said to have been crossing the border sooner, leading to the term sooners, which eventually became the state's official nickname. Deliberations to make the territory into a state began near the end of the 19th century, when the Curtis Act continued the allotment of Indian tribal land.
20th and 21st centuries
Attempts to create an all-Indian state named Oklahoma and a later attempt to create an all-Indian state named Sequoyah failed but the Sequoyah Statehood Convention of 1905 eventually laid the groundwork for the Oklahoma Statehood Convention, which took place two years later. On June 16, 1906, Congress enacted a statute authorizing the people of the Oklahoma and Indian Territories (as well what would become the states of Arizona and New Mexico) to form a constitution and state government in order to be admitted as a state. On November 16, 1907, President Theodore Roosevelt issued Presidential Proclamation no. 780, establishing Oklahoma as the 46th state in the Union.
The new state became a focal point for the emerging oil industry, as discoveries of oil pools prompted towns to grow rapidly in population and wealth. Tulsa eventually became known as the "Oil Capital of the World" for most of the 20th century and oil investments fueled much of the state's early economy. In 1927, Oklahoman businessman Cyrus Avery, known as the "Father of Route 66", began the campaign to create U.S. Route 66. Using a stretch of highway from Amarillo, Texas to Tulsa, Oklahoma to form the original portion of Highway 66, Avery spearheaded the creation of the U.S. Highway 66 Association to oversee the planning of Route 66, based in his hometown of Tulsa.
Oklahoma also has a rich African-American history. Many Black towns, founded by the Freedmen of the Five Tribes during Reconstruction, thrived in the early 20th century with the arrival of Black Exodusters who migrated from neighboring states, especially Kansas. The politician Edward P. McCabe encouraged Black settlers to come to what was then Indian Territory. McCabe discussed with President Theodore Roosevelt the possibility of making Oklahoma a majority-Black state.
By the early 20th century, the Greenwood district of Tulsa was one of the most prosperous African-American communities in the United States. Jim Crow laws had established racial segregation since before the start of the 20th century, but Tulsa's Black residents had created a thriving area.
Social tensions were exacerbated by the revival of the Ku Klux Klan after 1915. The Tulsa race massacre broke out in 1921, with White mobs attacking Black people and carrying out a pogrom in Greenwood. In one of the costliest episodes of racist violence in American history, sixteen hours of rioting resulted in the destruction of 35 city blocks, $1.8 million in property damage, and an estimated death toll of between 75 and 300 people. By the late 1920s, the Ku Klux Klan had declined to negligible influence within the state.
During the 1930s, parts of the state began to suffer from the consequences of poor farming practices. This period was known as the Dust Bowl, throughout which areas of Kansas, Texas, New Mexico and northwestern Oklahoma were hampered by long periods of little rainfall, strong winds, abnormally high temperatures, and most notably, severe dust storms sending thousands of farmers into poverty and forcing them to relocate to more fertile areas of the western United States. Over a twenty-year period ending in 1950, the state saw its only historical decline in population, dropping 6.9 percent as impoverished families migrated out of the state after the Dust Bowl.
Soil and water conservation projects markedly changed practices in the state and led to the construction of massive flood control systems and dams; they built hundreds of reservoirs and man-made lakes to supply water for domestic needs and agricultural irrigation. By the 1960s, Oklahoma had created more than 200 lakes, the most in the nation.
In 1995, Oklahoma City was the site of the most destructive act of domestic terrorism in American history. The Oklahoma City bombing of April 19, 1995, in which Timothy McVeigh detonated a large, crude explosive device outside the Alfred P. Murrah Federal Building, killed 168 people, including 19 children. For his crime, McVeigh was executed by the federal government on June 11, 2001. His accomplice, Terry Nichols, is serving life in prison without parole for helping plan the attack and prepare the explosive.
On May 31, 2016, several cities experienced record setting flooding.
On July 9, 2020, the Supreme Court of the United States determined in McGirt v. Oklahoma that the reservations of the Five Tribes, comprising much of Eastern Oklahoma, were never disestablished by Congress and thus are still "Indian Country" for the purposes of criminal law.

Oklahoma is the 20th-largest state in the United States, covering an area of 69,899 square miles (181,040 km2), with 68,595 square miles (177,660 km2) of land and 1,304 square miles (3,380 km2) of water. It lies partly in the Great Plains near the geographical center of the 48 contiguous states. It is bordered on the east by Arkansas and Missouri, on the north by Kansas, on the northwest by Colorado, on the far west by New Mexico, and on the south and near-west by Texas.
Oklahoma's border with Kansas was defined as the 37th Parallel in the 1854 Kansas-Nebraska Act. This was disputed with the Cherokee and Osage Nations which claimed their border extended North of this line and could not be part of the Kansas Territory. This was resolved in 1870 with the Drum Creek Treaty, which reestablished Kansas's southern border as the 37th parallel. This also applied to the then No-Man's Land that became the Oklahoma Panhandle.
The Oklahoma-Texas border consists of the Red River in the south and the 100th meridian west as the western border between Oklahoma and the Texas Panhandle. These were first established in the 1819 Adams–Onís Treaty between the United States and Spain.
The Oklahoma panhandle was originally part of the Panhandle of the Republic of Texas, but when Texas joined the Union as a slave state, it could not retain any lands north of 36 degrees 30 minutes, as specified in the Missouri Compromise. The Panhandle existed as a no-man's land until 1907 when Oklahoma acquired the territory upon gaining statehood.
Oklahoma's Eastern border is divided between Missouri and Arkansas. The Missouri-Oklahoma border is defined as the Meridian passing through the Kawsmouth, where the Kansas River meets the Missouri River. This is the same Meridian as the Kansas-Missouri border.
The Oklahoma-Arkansas border was originally defined by two lines: the borders between Arkansas and the Cherokee and Choctaw Reservations. This formed two diagonal lines meeting at the western edge of Fort Smith Arkansas, with one line running northeast from the Red River and the other running southeast from the Oklahoma-Arkansas-Missouri border. The Choctaw-Arkansas border was established in the 1820 Treaty of Doak's Sand, and later refined in the 1830 Treaty of Dancing Rabbit Creek. These treaties left a 57-acre exclave of the Choctaw reservation bounded by Arkansas, the Arkansas River and the Poteau River. This became the site of a smuggling camp called "Coke Hill", noted mostly for its importance in cocaine smuggling.
After Petitioning congress to hand over jurisdiction, the 57 acres was given to Arkansas in 1905. The 1985 US Supreme Court Case Oklahoma v. Arkansas decided the land would remain Arkansas, even though the Choctaw had not been notified or asked about the territory being handed over. Therefore, the Poteau River serves as the Oklahoma-Arkansas boundary for approximately 1 mile, reducing the Choctaw Reservation and later Oklahoma by 57 acres as established in the treaties of the early 1800s.
Oklahoma is between the Great Plains and the Ozark Plateau in the Gulf of Mexico watershed, generally sloping from the high plains of its western boundary to the low wetlands of its southeastern boundary. Its highest and lowest points follow this trend, with its highest peak, Black Mesa, at 4,973 feet (1,516 m) above sea level, situated near its far northwest corner in the Oklahoma Panhandle. The state's lowest point is on the Little River near its far southeastern boundary near the town of Idabel, which dips to 289 feet (88 m) above sea level.
Among the most geographically diverse states, Oklahoma is one of four to harbor more than 10 distinct ecological regions, with 11 in its borders—more per square mile than in any other state. Its western and eastern halves, however, are marked by extreme differences in geographical diversity: Eastern Oklahoma touches eight ecological regions and its western half contains three. Although having fewer ecological regions Western Oklahoma contains many rare, relic species.
Oklahoma has four primary mountain ranges: the Ouachita Mountains, the Arbuckle Mountains, the Wichita Mountains, and the Ozark Mountains. Contained within the U.S. Interior Highlands region, the Ozark and Ouachita Mountains are the only major mountainous region between the Rocky Mountains and the Appalachians. A portion of the Flint Hills stretches into north-central Oklahoma, and near the state's eastern border, The Oklahoma Tourism & Recreation Department regards Cavanal Hill as the world's tallest hill; at 1,999 feet (609 m), it fails their definition of a mountain by one foot.
The semi-arid high plains in the state's northwestern corner harbor few natural forests; the region has a rolling to flat landscape with intermittent canyons and mesa ranges like the Glass Mountains. Partial plains interrupted by small, sky island mountain ranges like the Antelope Hills and the Wichita Mountains dot southwestern Oklahoma; transitional prairie and oak savannas cover the central portion of the state. The Ozark and Ouachita Mountains rise from west to east over the state's eastern third, gradually increasing in elevation in an eastward direction.
More than 500 named creeks and rivers make up Oklahoma's waterways, and with 200 lakes created by dams, it holds the nation's highest number of artificial reservoirs. Most of the state lies in two primary drainage basins belonging to the Red and Arkansas Rivers, though the Lee and Little Rivers also contain significant drainage basins.

Flora and fauna
Due to Oklahoma's location at the confluence of many geographic regions, the state's climatic regions have a high rate of biodiversity. Forests cover 24 percent of Oklahoma and prairie grasslands composed of shortgrass, mixed-grass, and tallgrass prairie, harbor expansive ecosystems in the state's central and western portions, although cropland has largely replaced native grasses. Where rainfall is sparse in the state's western regions, shortgrass prairie and shrublands are the most prominent ecosystems, though pinyon pines, red cedar (junipers), and ponderosa pines grow near rivers and creek beds in the panhandle's far western reaches. Southwestern Oklahoma contains many rare, disjunct species, including sugar maple, bigtooth maple, nolina, and Texas live oak.
Marshlands, cypress forests, and mixtures of shortleaf pine, loblolly pine, blue palmetto, and deciduous forests dominate the state's southeastern quarter, while mixtures of largely post oak, elm, red cedar (Juniperus virginiana), and pine forests cover northeastern Oklahoma.
The state holds populations of white-tailed deer, mule deer, antelope, coyotes, mountain lions, bobcats, elk, and birds such as quail, doves, cardinals, bald eagles, red-tailed hawks, and pheasants. In prairie ecosystems, American bison, greater prairie chickens, badgers, and armadillo are common, and some of the nation's largest prairie dog towns inhabit shortgrass prairie in the state's panhandle. The Cross Timbers, a region transitioning from prairie to woodlands in Central Oklahoma, harbors 351 vertebrate species. The Ouachita Mountains are home to black bear, red fox, gray fox, and river otter populations, which coexist with 328 vertebrate species in southeastern Oklahoma. Also in southeastern Oklahoma lives the American alligator.
Oklahoma has fifty-one state parks, six national parks or protected regions, two national protected forests or grasslands, and a network of wildlife preserves and conservation areas. Six percent of the state's 10 million acres (40,000 km2) of forest is public land, including the western portions of the Ouachita National Forest, the largest and oldest national forest in the Southern United States.
With 39,000 acres (160 km2), the Tallgrass Prairie Preserve in north-central Oklahoma is the largest protected area of tallgrass prairie in the world and is part of an ecosystem that encompasses only ten percent of its former land area, once covering fourteen states. In addition, the Black Kettle National Grassland covers 31,300 acres (127 km2) of prairie in southwestern Oklahoma. The Wichita Mountains Wildlife Refuge is the oldest and largest of nine National Wildlife Refuges in the state and was founded in 1901, encompassing 59,020 acres (238.8 km2).
Of Oklahoma's federally protected parks or recreational sites, the Chickasaw National Recreation Area is the largest, with 9,898.63 acres (40.0583 km2). Other sites include the Santa Fe and Trail of Tears national historic trails, the Fort Smith and Washita Battlefield national historic sites, and the Oklahoma City National Memorial.
Oklahoma is in a humid subtropical region that lies in a transition zone between semiarid further to the west, humid continental to the north, and humid subtropical to the east and southeast. Most of the state lies in an area known as Tornado Alley characterized by frequent interaction between cold, dry air from Canada, warm to hot, dry air from Mexico and the Southwestern U.S., and warm, moist air from the Gulf of Mexico. The interactions between these three contrasting air currents produces severe weather (severe thunderstorms, damaging thunderstorm winds, large hail and tornadoes) with a frequency virtually unseen anywhere else on planet Earth. An average 62 tornadoes strike the state per year—one of the highest rates in the world.
Because of Oklahoma's position between zones of differing prevailing temperature and winds, weather patterns within the state can vary widely over relatively short distances, and they can change drastically in a short time. On November 11, 1911, the temperature at Oklahoma City reached 83 °F (28 °C) (the record high for that date), then a cold front of unprecedented intensity slammed across the state, causing the temperature to reach 17 °F (−8 °C) (the record low for that date) by midnight. This type of phenomenon is also responsible for many of the tornadoes in the area, such as the 1912 Oklahoma tornado outbreak when a warm front traveled along a stalled cold front, resulting in an average of about one tornado per hour.
The humid subtropical climate (Köppen Cfa) of central, southern, and eastern Oklahoma is influenced heavily by southerly winds bringing moisture from the Gulf of Mexico. Traveling westward, the climate transitions progressively toward a semiarid zone (Köppen BSk) in the high plains of the Panhandle and other western areas from about Lawton westward, less frequently touched by southern moisture. Precipitation and temperatures decline from east to west accordingly, with areas in the southeast averaging an annual temperature of 62 °F (17 °C) and an annual rainfall of generally over 40 in (1,020 mm) and up to 56 in (1,420 mm), while areas of the (higher-elevation) panhandle average 58 °F (14 °C), with annual rainfall under 17 in (430 mm).
Over almost all of Oklahoma, winter is the driest season. Average monthly precipitation increases dramatically in the spring to a peak in May, the wettest month over most of the state, with its frequent and not uncommonly severe thunderstorm activity. Early June can still be wet, but most years see a marked decrease in rainfall during June and early July. Mid-summer (July and August) represents a secondary dry season over much of Oklahoma, with long stretches of hot weather with only sporadic thunderstorm activity not uncommon many years. Severe drought is common in the hottest summers, such as those of 1934, 1954, 1980 and 2011, all of which featured weeks on end of virtual rainlessness and highs well over 100 °F (38 °C). Average precipitation rises again from September to mid-October, representing a secondary wetter season, then declines from late October through December.
The entire state frequently experiences temperatures above 100 °F (38 °C) or below 0 °F (−18 °C), though below-zero temperatures are rare in south-central and southeastern Oklahoma. Snowfall ranges from an average of less than 4 in (102 mm) in the south to just over 20 in (508 mm) on the border of Colorado in the panhandle. The state is home to the Storm Prediction Center, the National Severe Storms Laboratory, and the Warning Decision Training Division, all part of the National Weather Service and in Norman.

Cities and towns
Oklahoma had 598 incorporated places in 2010, including four cities over 100,000 in population and 43 over 10,000. Two of the fifty largest cities in the United States are in Oklahoma, Oklahoma City and Tulsa, and sixty-five percent of Oklahomans live within their metropolitan areas, or spheres of economic and social influence defined by the United States Census Bureau as a metropolitan statistical area. Oklahoma City, the state's capital and largest city, had the largest metropolitan area in the state in 2020, with 1,425,695 people, and the metropolitan area of Tulsa had 1,015,331 residents. Between 2000 and 2010, the leading cities in population growth were Blanchard (172.4%), Elgin (78.2%), Jenks (77.0%), Piedmont (56.7%), Bixby (56.6%), and Owasso (56.3%).
In descending order of population, Oklahoma's largest cities in 2010 were: Oklahoma City (579,999, +14.6%), Tulsa (391,906, −0.3%), Norman (110,925, +15.9%), Broken Arrow (98,850, +32.0%), Lawton (96,867, +4.4%), Edmond (81,405, +19.2%), Moore (55,081, +33.9%), Midwest City (54,371, +0.5%), Enid (49,379, +5.0%), and Stillwater (45,688, +17.0%). Of the state's ten largest cities, three are outside the metropolitan areas of Oklahoma City and Tulsa, and only Lawton has a metropolitan statistical area of its own as designated by the United States Census Bureau, though the metropolitan statistical area of Fort Smith, Arkansas extends into the state.
Under Oklahoma law, municipalities are divided into two categories: cities, defined as having more than 1,000 residents, and towns, with under 1,000 residents. Both have legislative, judicial, and public power within their boundaries, but cities can choose between a mayor–council, council–manager, or strong mayor form of government, while towns operate through an elected officer system.

|U.S. Decennial Census|
From a 1920 U.S. census population of 2,028,283, Oklahoma's population has continued to increase. At the 2010 census, its population was 3,751,675. The 2020 Census revealed its population to be was 3,959,353, an 5.5% increase since 2010. A 2022 American Community Survey estimate found that the population had surpassed 4 million residents for the first time. Among the states of the South Central region, Oklahoma had the second-largest population increase from 2010 to 2020, behind Texas.
Of the state's total resident population, approximately 236,882 were immigrants according to a study in 2018, making up 6% of the state's population at the time. Most of its immigrant population came from Mexico (45%), Vietnam (5%), India (5%), Germany (3%), and Guatemala (3%). In the state, 246,550 residents were native-born Americans who had at least one immigrant parent. An estimated 85,000 immigrants were undocumented with 125,989 Oklahomans having lived with at least one undocumented family member between 2010 and 2014. Immigrants to Oklahoma have contributed more than a billion U.S. dollars in taxes in 2018. In 2011, the U.S. Census Bureau's American Community Survey data from 2005 to 2009 indicated about 5% of Oklahoma's residents were born outside the United States. This was lower than the national figure (about 12.5% of U.S. residents were foreign-born).
In 2010, the center of population of Oklahoma was in Lincoln County near the town of Sparks.
According to HUD's 2022 Annual Homeless Assessment Report, there were an estimated 3,754 homeless people in Oklahoma. 
Race and ethnicity
As with majority of the U.S., Oklahoma has experienced diversification since the beginning of the 21st century; in 1940, 90.1% of the state's population was non-Hispanic white; in 2020, 75.5% of the population was white, down from 1990's 81% yet up from 2010's 72.2%. Among its population at the 2020 census, the remainder of its increasingly diverse population was 11.9% Hispanic or Latino of any race, 16% American Indian and Alaska Native, 9.7% Black or African American, 3.1% Asian, 0.4% Native Hawaiian and other Pacific Islander, and 9% some other race. According to the 2010 census, 8.6% were American Indian and Alaska Native, 7.4% Black or African American, 1.7% Asian, 0.1% Native Hawaiian and other Pacific Islander, 4.1% from some other race and 5.9% of two or more races; 8.9% of Oklahoma's population were of Hispanic, Latino, or Spanish origin (they may be of any race).

In 2005, Oklahoma's estimated ancestral makeup was 14.5% German, 13.1% American, 11.8% Irish, 9.6% English, 8.1% African American, and 11.4% Native American (including 7.9% Cherokee), though the percentage of people claiming American Indian as their only race was 8.1%. Most people from Oklahoma who self-identify as having American ancestry are of overwhelmingly English and Scots-Irish ancestry with significant amounts of Scottish, Welsh and Irish inflection as well.
In 2011, 47.3% of Oklahoma's population younger than age 1 were minorities, meaning they had at least one parent who was not non-Hispanic white.
The English language has been official in the state of Oklahoma since 2010. The variety of North American English spoken is called Oklahoma English, and this dialect is quite diverse with its uneven blending of features of North Midland, South Midland, and Southern dialects. In 2000, 2,977,187 Oklahomans—92.6% of the resident population, five years or older—spoke only English at home, a decrease from 95% in 1990. 238,732 Oklahoma residents reported speaking a language other than English at home in the 2000 census, about 7.4% of the state's population.
Native American languages
The two most commonly spoken native North American languages are Cherokee and Choctaw, with 10,000 Cherokee speakers living within the Cherokee Nation tribal jurisdiction area of eastern Oklahoma and another 10,000 Choctaw speakers living in the Choctaw Nation directly south of the Cherokees. Cherokee is an official language in the Cherokee Nation tribal jurisdiction area and in the United Keetoowah Band of Cherokee Indians.
Twenty-five Native American languages are spoken in Oklahoma, second only to California. However, only Cherokee, if any, exhibits some language vitality at present. Ethnologue sees Cherokee as moribund because the only remaining active users of the language are members of the grandparent generation and older.

Oklahoma has a few ethnic-oriented TV stations broadcasting in Spanish and Asian languages, and there is some Native American programming. TBN, a Christian religious television network, has a studio in Tulsa, and built its first entirely TBN-owned affiliate in Oklahoma City in 1980.

Transportation in Oklahoma is generated by an anchor system of Interstate Highways, inter-city rail lines, airports, inland ports, and mass transit networks. Situated along an integral point in the United States Interstate network, Oklahoma contains three primary Interstate highways and four auxiliary Interstate Highways. In Oklahoma City, Interstate 35 intersects with Interstate 44 and Interstate 40, forming one of the most important intersections along the United States highway system.
More than 12,000 miles (19,000 km) of roads make up the state's major highway skeleton, including state-operated highways, ten turnpikes or major toll roads, and the longest drivable stretch of Route 66 in the nation. In 2008, Interstate 44 in Oklahoma City was Oklahoma's busiest highway, with a daily traffic volume of 123,300 cars. In 2010, the state had the nation's third-highest number of bridges classified as structurally deficient, with nearly 5,212 bridges in disrepair, including 235 National Highway System Bridges.
Oklahoma's largest commercial airport is Will Rogers World Airport in Oklahoma City, averaging a yearly passenger count of more than 3.5 million (1.7 million boardings) in 2010. Tulsa International Airport, the state's second-largest commercial airport, served more than 1.3 million boardings in 2010. Between the two, six airlines operate in Oklahoma. In terms of traffic, R. L. Jones Jr. (Riverside) Airport in Tulsa is the state's busiest airport, with 335,826 takeoffs and landings in 2008. Oklahoma has more than 150 public-use airports.
Oklahoma is connected to the nation's rail network via Amtrak's Heartland Flyer, its only regional passenger rail line. It currently stretches from Oklahoma City to Fort Worth, Texas, though lawmakers began seeking funding in early 2007 to connect the Heartland Flyer to Tulsa.
Two inland ports on rivers serve Oklahoma: the Port of Muskogee and the Tulsa Port of Catoosa. The Tulsa Port of Catoosa is the one of the United States' most inland international ports, at head of navigation of the McClellan–Kerr Arkansas River Navigation System, which connects barge traffic from Tulsa and Muskogee to the Mississippi River. The port ships over two million tons of goods annually and is a designated foreign trade zone.

Law and government
Oklahoma is a constitutional republic with a government modeled after the federal government of the United States, with executive, legislative, and judicial branches. The state has 77 counties with jurisdiction over most local government functions within each respective domain, five congressional districts, and a voting base with a majority in the Republican Party. State officials are elected by plurality voting in the state of Oklahoma.
Oklahoma has capital punishment as a legal sentence, and the state has had (between 1976 through mid-2011) the highest per capita execution rate in the nation. Authorized methods of execution include the Electric chair, the Gas chamber and the Firing Squad.
In a 2020 study, Oklahoma was ranked as the 14th most difficult state for citizens to vote in.
The Legislature of Oklahoma consists of the Senate and the House of Representatives. As the lawmaking branch of the state government, it is responsible for raising and distributing the money necessary to run the government. The Senate has 48 members serving four-year terms, while the House has 101 members with two-year terms. The state has a term limit for its legislature that restricts any one person to twelve cumulative years service between both legislative branches.
Oklahoma's judicial branch consists of the Oklahoma Supreme Court, the Oklahoma Court of Criminal Appeals, and 77 District Courts that each serve one county. The Oklahoma judiciary also contains two independent courts: a Court of Impeachment (for impeachment trials) and the Oklahoma Court on the Judiciary. Oklahoma has two courts of last resort: the state Supreme Court hears civil cases, and the state Court of Criminal Appeals hears criminal cases (this split system exists only in Oklahoma and neighboring Texas). Judges of those two courts, as well as the Court of Civil Appeals are appointed by the Governor upon the recommendation of the state Judicial Nominating Commission, and are subject to a non-partisan retention vote on a six-year rotating schedule.
The executive branch consists of the Governor, their staff, and other elected officials. The principal head of government, the Governor is the chief executive of the Oklahoma executive branch, serving as the ex officio Commander-in-chief of the Oklahoma National Guard when not called into Federal use and reserving the power to veto bills passed through the Legislature. The responsibilities of the Executive branch include submitting the budget, ensuring state laws are enforced, and ensuring peace within the state is preserved.
The state is divided into 77 counties that govern locally, each headed by a three-member council of elected commissioners, a tax assessor, clerk, court clerk, treasurer, and sheriff. While each municipality operates as a separate and independent local government with executive, legislative and judicial power, county governments maintain jurisdiction over both incorporated cities and non-incorporated areas within their boundaries, and have executive power but no legislative or judicial power. Both county and municipal governments collect taxes, employ a separate police force, hold elections, and operate emergency response services within their jurisdiction. Other local government units include school districts, technology center districts, community college districts, rural fire departments, rural water districts, and other special use districts.
Thirty-nine Native American tribal governments are based in Oklahoma, each holding limited powers within designated areas. While Indian reservations are typical in most of the United States, they are not present in Oklahoma, tribal governments hold land granted during the Indian Territory era, but with limited jurisdiction and no control over state governing bodies such as municipalities and counties. Tribal governments are recognized by the United States as quasi-sovereign entities with executive, judicial, and legislative powers over tribal members and functions, but are subject to the authority of the United States Congress to revoke or withhold certain powers. The tribal governments are required to submit a constitution and any subsequent amendments to the United States Congress for approval.
Oklahoma has 11 substate districts including the two large Councils of Governments, INCOG in Tulsa (Indian Nations Council of Governments) and ACOG (Association of Central Oklahoma Governments).
During the first half-century of statehood, Oklahoma was considered a Democratic stronghold, being carried by the Republican Party in only two presidential elections (1920 and 1928). After the 1948 election, the state turned firmly Republican. Although registered Republicans were a minority in the state until 2015, Oklahoma has been carried by Republican presidential candidates in all but one election since 1952: Lyndon B. Johnson's 1964 landslide victory. Every single county in the state has been won by the Republican candidate in each election since 2004. Oklahoma City was the largest city in the United States carried by Republican Donald Trump in both the 2016 and 2020 elections.
Democrats are strongest in the eastern part of the state and Little Dixie, as well as the most heavily African American and inner parts of Oklahoma City and Tulsa. In addition, precincts with high concentrations of Native Americans (who form 8.6% of the state’s population) also tend to support the Democratic Party.
Following the 2000 census, the Oklahoma delegation to the U.S. House of Representatives was reduced from six to five representatives, each serving one congressional district. In the current Congress, Republicans comprise Oklahoma's entire delegation.

State law codifies Oklahoma's state emblems and honorary positions; the Oklahoma Senate or House of Representatives may adopt resolutions designating others for special events and to benefit organizations. In 2012 the House passed HCR 1024, which would change the state motto from "Labor Omnia Vincit" to "Oklahoma—In God We Trust!" The author of the resolution stated a constituent researched the Oklahoma Constitution and found no "official" vote regarding "Labor Omnia Vincit", therefore opening the door for an entirely new motto.
