| Elections in South Carolina |

The 1940 United States House of Representatives elections in South Carolina were held on November 5, 1940 to select six Representatives for two-year terms from the state of South Carolina. All five incumbents who ran were re-elected and the open seat in the 1st congressional district was retained by the Democrats. The composition of the state delegation thus remained solely Democratic.
