The 2018 South Carolina gubernatorial election was held on November 6, 2018, to elect the governor of South Carolina. Incumbent Republican Governor Henry McMaster, who took office after Nikki Haley resigned to become U.S. Ambassador to the United Nations, ran for election to a full term. The primary was held on June 12, with the Democrats nominating State Representative James E. Smith Jr. McMaster failed to win a majority of the vote, and then defeated John Warren in the Republican runoff on June 26. In the general election, McMaster defeated Smith, winning election to a full term.
Republicans won their fifth straight gubernatorial election in the state, their longest such streak in history.
