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. Candidates had until June 1, 2020 to file to run for the open seat, or to drop out if they had already filed. The U.S. Senate primaries were held on August 4, 2020.

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.

Primary debate In a live-streamed debate on May 22, 2020, in a ballroom devoid of spectators due to the COVID-19 pandemic, all five major candidates praised president Donald Trump. Kobach took on his opponents who all agreed that he could not win the general election against presumptive Democratic nominee, Bollier.Five GOP candidates for U.S. Senate spar on electability, threat of Democrat victory, Capital Journal, Tim Carpenter, May 23, 2020. Retrieved May 25, 2020. Marshall said, "We cannot afford to send a failed candidate back this fall who will lose to Barbara Bollier and hand the Senate majority over to Chuck Schumer." "Instead, we need to send a tried and trusted friend of President Trump." Referring to Marshall, Kobach replied, "Do you want a go-along-to-get-along kind of senator, a gutless wonder who never takes a stand, or, do you want someone who poses a threat?" Hamilton said voters didn't have to choose between Kobach, who couldn't win, and a moderate Marshall, in whose behest the state party leaders had urged Senator Wagle and Lindstrom, to drop out of the race. Objecting to the party pressure, Lindstrom characterized his opponents as "shortsighted, self-serving ... career politicians who are divisive, controversial," and, "have a record of losing elections." Wagle touted her own candidacy, saying, "It's very, very important that we send a leader to the U.S. Senate who is articulate, who is persuasive, who other people respect. ... I'm the one who's already debated Barbara Bollier. ... I win on the Senate floor. I've beat (sic) her numerous times ... the conservative voice that can beat that liberal voice in the U.S. Senate," she said. In response to a claim that he would not prioritize the issue of agriculture, Marshall said, "Fake news and another lie by Kris Kobach."
