The 2020 United States Senate election in Kansas was held on November 3, 2020, to elect a member of the United States Senate to represent the State of Kansas, concurrently with the 2020 U.S. presidential election, as well as other elections to the United States Senate, elections to the United States House of Representatives and various state and local elections.

On January 4, 2019, incumbent Republican Senator Pat Roberts announced he would not run for a fifth term.^[1] Candidates had until June 1, 2020 to file to run for the open seat or to drop out if they already filed.^[2] The U.S. Senate primaries were held on August 4, 2020.^[3][4]

Republican U.S. Representative Roger Marshall was considered a narrow favorite based on polling, but he won by around 11 points, a larger margin than most experts predicted. However, this was the first Senate election since 1978 where a Democrat won Shawnee County, the first Senate election since 1974 where a Democrat won Riley County, and the first Senate election ever in Kansas's history where a Democrat won Johnson County; all three counties were also flipped by Democrat Joe Biden in the concurrent presidential election.
