The 2020 United States House of Representatives election in South Dakota was held on November 3, 2020, to elect the U.S. representative from South Dakota's at-large congressional district. The election coincided with the 2020 U.S. presidential election, as well as other elections to the House of Representatives, elections to the United States Senate and various state and local elections.
