List of Oklahoma ballot measures

The Legislature of the State of Oklahoma is the state legislative branch of the U.S. state of Oklahoma. The Oklahoma House of Representatives and Oklahoma Senate are the two houses that make up the bicameral state legislature. There are 101 state representatives, each serving a two-year term, and 48 state senators, who serve four-year terms that are staggered so only half of the Oklahoma Senate districts are eligible in each election cycle. Legislators are elected directly by the people from single member districts of equal population. The Oklahoma Legislature meets annually in the Oklahoma State Capitol in Oklahoma City.

The President pro tempore of the Oklahoma Senate is the second-highest-ranking official of the Oklahoma Senate and the highest-ranking state senator. The Oklahoma Constitution designates the Lieutenant Governor of Oklahoma as the highest-ranking official, serving ex officio as President of the Senate, even though the lieutenant governor only votes in the case of a tie. During the lieutenant governor's absence, the president pro tempore presides over sessions. By longstanding custom, the lieutenant governor presides over sessions devoted to ceremonial purposes, while the bulk of the legislative management and political power is reserved for the president pro tempore, who is elected directly by the Oklahoma Senate.

The governor of Oklahoma is the head of government of the U.S. state of Oklahoma. Under the Oklahoma Constitution, the governor serves as the head of the Oklahoma executive branch, of the government of Oklahoma. The governor is the ex officio commander-in-chief of the Oklahoma National Guard when not called into federal use. Despite being an executive branch official, the governor also holds legislative and judicial powers. The governor's responsibilities include making yearly "State of the State" addresses to the Oklahoma Legislature, submitting the annual state budget, ensuring that state laws are enforced, and that the peace is preserved. The governor's term is four years in length.

The lieutenant governor of Oklahoma is the second-highest executive official of the state government of Oklahoma.

The lieutenant governor also serves as the president of the Oklahoma Senate, and may cast a vote to break ties in that chamber.

The Oklahoma Judicial Nominating Commission is the judicial nominating commission of the U.S. state of Oklahoma. It selects potential justices and judges for gubernatorial appointments for judges for state appellate courts.

Sharia is a body of religious law that forms a part of the Islamic tradition. It is derived from the religious precepts of Islam and is based on the sacred scriptures of Islam, particularly the Quran and the Hadith. In Arabic, the term sharīʿah refers to God's immutable divine law and is contrasted with fiqh, which refers to its human scholarly interpretations. The manner of its application in modern times has been a subject of dispute between Muslim fundamentalists and modernists.
