2020 Oklahoma elections

The 2020 United States presidential election in Oklahoma was held on Tuesday, November 3, 2020, as part of the 2020 United States presidential election in which all 50 states plus the District of Columbia participated. Oklahoma voters chose electors to represent them in the Electoral College via a popular vote, pitting the Republican Party's nominee, incumbent President Donald Trump, and running mate Vice President Mike Pence against Democratic Party nominee, former Vice President Joe Biden, and his running mate California Senator Kamala Harris. Oklahoma has seven electoral votes in the Electoral College.

The United States Electoral College is the group of presidential electors required by the Constitution to form every four years for the sole purpose of appointing the president and vice president. Each state and the District of Columbia appoints electors pursuant to the methods described by its legislature, equal in number to its congressional delegation. Federal office holders, including senators and representatives, cannot be electors. Of the current 538 electors, an absolute majority of 270 or more electoral votes is required to elect the president and vice president. If no candidate achieves an absolute majority there, a contingent election is held by the House of Representatives to elect the president and by the Senate to elect the vice president.

The 2020 United States Senate election in Oklahoma was held on November 3, 2020, to elect a member of the United States Senate to represent the State of Oklahoma, concurrently with the 2020 U.S. presidential election, as well as other elections to the United States Senate in other states and elections to the United States House of Representatives and various state and local elections. Incumbent Republican Senator Jim Inhofe won reelection to a fifth full term, defeating Democratic challenger Abby Broyles.
