The 2026 United States Senate election in Kansas will be held on November 3, 2026, to elect a member of the United States Senate to represent the state of Kansas. One-term Republican Senator Roger Marshall was elected in 2020 with 53.2% of the vote.[1]
Kansas is generally considered to be a Republican stronghold, having not elected a Democrat to the U.S. senate since 1932. Republicans control both U.S. Senate seats, all but two statewide offices, both houses of the Kansas Legislature, and all but one seat in its congressional delegation in Kansas's U.S. House congressional delegation.[2] Marshall was first elected in 2020, defeating Barbara Bollier by 11.4 points what was expected to be a close race.[3] However, Democrats control the governorship and lieutenant-governorship which they flipped from Republican control in 2018.[4]
