The 1950 South Dakota gubernatorial election was held on November 7, 1950. Incumbent Republican Governor George T. Mickelson was unable to seek re-election to a third term due to newly imposed term limits. Accordingly, a competitive race to replace him ensued. Attorney General Sigurd Anderson won a slim plurality in the Republican primary, barely exceeding 35% and narrowly avoiding having the Republican nomination sent to the state party convention. In the general election, Anderson faced State Representative Joe Robbie. Anderson easily defeated Robbie, winning his first term with 61% of the vote to Robbie's 39%.

State Representative Joe Robbie, who represented Davison County in the State House, was the only Democrat to file for the gubernatorial race, winning the nomination by default and removing the race from the primary election ballot.
