The 1900 South Carolina gubernatorial election was held on November 6, 1900 to select the governor of the state of South Carolina. Governor Miles Benjamin McSweeney won the Democratic primary and ran unopposed in the general election to win a term for governor in his own right.
The South Carolina Democratic Party held their primary for governor on August 28 and incumbent Governor McSweeney was the frontrunner. McSweeney favored the continuation of the state Dispensary which brought the backing of influential Senator and former Governor Ben Tillman. Prohibitionist James A. Hoyt won second place in the primary to advance to the runoff on September 11, but could not overcome McSweeney because the voters of the state simply did not want any alteration of an institution set up by Ben Tillman.
