The 2018 United States House of Representatives election in South Dakota was held on November 6, to elect the U.S. representative for South Dakota's at-large congressional district. The election coincided with other statewide, legislative, and local elections.
Incumbent Republican U.S. Representative Kristi Noem did not run for a fifth term and instead ran successfully for governor of South Dakota. This was the first open seat election since 2004, and the first time a male candidate was elected since 2002. This was the last U.S. House election in South Dakota until 2024 that a Democrat appeared on the November ballot.
