2022 United States Senate election in Oklahoma

The 2022 United States Senate election in Oklahoma was held on November 8, 2022, to elect a member of the United States Senate to represent the State of Oklahoma. Incumbent senator James Lankford won re-election to a second full term, defeating cybersecurity professional Madison Horn (no relation to former U.S. Representative Kendra Horn, who ran for the concurrent special election to the Class II seat) in a landslide, winning all 77 counties with more than 50% of the vote in each.

Lankford was first elected in 2014 special election with 68% of the vote, succeeding retiring fellow Republican Tom Coburn. He won re-election to a first full term in 2016 with 68% of the vote.

The primary elections for the Republican, Democratic, and Libertarian parties' nominations took place on June 28, 2022, with runoffs taking place on August 23, 2022. All candidates had to file between the days of April 13–15, 2022.

Despite his comfortable victory, with slightly over 64% of the vote received this was Lankford's worst performance in his career, as in each of his previous two elections he won nearly 68%. This also marked the best performance by a Democratic candidate since 2004 in the Class III seat.

Republican primary
On March 16, 2021, Jackson Lahmeyer announced his campaign for the Republican nomination for United States Senate seat held by James Lankford. While Lankford had not formally announced, he was expected to run for reelection. On April 6, Lankford officially announced he would seek reelection in an interview with the Tulsa World. The Oklahoman reported that Joan Farr announced her candidacy for the Oklahoma and Kansas U.S. Senate seats sometime in August. On September 28, state senator Nathan Dahm announced his campaign for Lankford's seat. In November the Tulsa World reported that Jessica Jean Garrison, the daughter of former state senator Earl Garrison, would also campaign in the contested Republican primary. On February 28, 2022, Nathan Dahm announced he had switched his campaign to the special election in the Class 2 seat. Jessica Jean Garrison also switched her campaign to the special election when filing. Lankford won the June primary with 67% of the vote.
