The 1934 South Carolina gubernatorial election was held on November 6, 1934, to select the governor of the state of South Carolina. Olin D. Johnston won the contested Democratic primary and ran unopposed in the general election becoming the 98th governor of South Carolina.
The South Carolina Democratic Party held their primary for governor in the summer of 1934 and it attracted many politicians because of the change in 1926 to the South Carolina constitution providing for a four-year term. Johnston emerged victorious from the runoff against former Governor Cole Blease and ran without opposition on account of South Carolina's effective status as a one-party state.
