The 2026 United States Senate election in Oklahoma is scheduled for November 3, 2026. Incumbent Senator Markwayne Mullin has not announced whether he will seek reelection.

Background

The 2026 United States Senate election in Oklahoma is scheduled for November 3, 2026. Markwayne Mullin is the incumbent.[1] After former President Donald Trump won the 2024 United States presidential election, Mullin was rumored as a contender for U.S. Secretary of Interior.[2] Mullin's resignation would have affected the open 2026 Oklahoma gubernatorial election and if Mullin resigned 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]
