The 1946 United States House of Representatives elections in South Carolina were held on November 5, 1946, to select six Representatives for two-year terms from the state of South Carolina. Five incumbents were re-elected, but Butler B. Hare of the 3rd congressional district was defeated in the Democratic primary by W.J. Bryan Dorn. The seat remained with the Democrats and the composition of the state delegation remained solely Democratic.
Incumbent Democratic Congressman Joseph R. Bryson of the 4th congressional district, in office since 1939, defeated Charles C. Moore in the Democratic primary and was unopposed in the general election.
