The 2026 United States Senate election in Wyoming will be held on November 3, 2026, to elect a member of the United States Senate to represent the state of Wyoming. Primary elections will be held on August 18, 2026. Republican Senator Cynthia Lummis, who was elected in 2020, declined to seek reelection to a second term.
Wyoming is considered to be a deeply red state at the federal and state levels, with Donald Trump overwhelmingly winning the state in 2024 by more than 45 points. Republicans control both houses of the Wyoming Legislature with large supermajorities, the state's only congressional district, and all statewide executive offices. Wyoming has been represented in the U.S. Senate exclusively by Republicans since 1977, Democrats have not won in the state since 1970, and in this seat since 1954. Cynthia Lummis was first elected in 2020, defeating zoologist Merav Ben-David by 46 percentage points to succeed longtime incumbent Senator Mike Enzi, who opted to retire. Wyoming is unique in its status as the "reddest" state in the entire nation and it also is the least-populated state in the country. Lummis raised $500,000 for her re-election bid in second quarter of 2025.
