The 2026 South Dakota elections will be held in the U.S. state of South Dakota on November 3, 2026, alongside the nationwide midterm elections. Elections will be held for a United States Senate seat and the state's U.S. House of Representatives at-large seat as well as elections for governor, most other statewide executive offices, all seats in the South Dakota Senate and House of Representatives, and other elections. Primary elections will be held on June 2, 2026, alongside several other local and municipal elections.
A red state, South Dakota has not elected a Democrat to federal office since 2008, when incumbent senator Tim Johnson and incumbent U.S. representative Stephanie Herseth Sandlin both won re-election. Despite not electing Democrats to statewide or federal office, Senate Minority Leader Billie Sutton came within 11,500 votes of winning the governorship in 2018, the closest gubernatorial race since the state moved to four-year gubernatorial terms, beginning in 1974. Republicans have held control of both chambers of the state legislature since 1995.
