The 2026 South Dakota gubernatorial election is scheduled to take place on November 3, 2026, to elect the governor of South Dakota. The primary elections were held on June 2, 2026, and since no candidate received over 35% in the republican primary, a runoff election will take place on July 28.[1]

Incumbent Republican Larry Rhoden, who ascended to the office of governor in 2025 after Kristi Noem resigned to become secretary of homeland security, is running for his first full term in office.[2] Rhoden had previously been serving as lieutenant governor under Noem since the two took office in 2019.[2] Democrats have not won a gubernatorial election in South Dakota since 1974.

As no candidate received 35% of the primary vote, a primary runoff will be held between the top two candidates. This will be first runoff ever held in the state since the adoption of a 1985 law requiring runoffs in gubernatorial and Congressional primaries when a candidate fails to receive 35% of the vote.[45]
