The 2026 United States Senate election in Oklahoma will be held on November 3, 2026, to elect a member of the U.S. Senate to represent the state of Oklahoma. Primary elections will be held on June 16, 2026. Incumbent senator Markwayne Mullin, first elected in the 2022 special election, has announced that he will seek reelection for his first full term in office.[1]
Background
After former President Donald Trump won the 2024 United States presidential election, incumbent Markwayne Mullin was rumored as a contender for U.S. Secretary of Interior.[2] Mullin's resignation would have affected the gubernatorial election, as governor Kevin Stitt would have appointed a replacement who must sign a potentially unenforceable[a] oath promising not to run for reelection in 2026.[3] Mullin was not appointed Secretary of Interior.[4]

In late 2024, incumbent Markwayne Mullin was rumored as a potential appointee in a second Trump administration, triggering speculation on which Republicans could run for a hypothetical open Senate seat in 2026.[3]
