The 1936 United States House of Representatives elections in South Carolina were held on November 2, 1936, 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 4th congressional district was retained by the Democrats. The composition of the state delegation thus remained solely Democratic.
There was a split in the South Carolina Republican Party between the Tolbert and Seabrook factions because each side wanted to be the arbiter of the spoils system should a national Republican victory occur. Therefore, they both offered their own slate of candidates for the federal contests and they were competing against each other, not the Democrats, to show the national Republican Party that they held more sway in the state.
Incumbent Democratic Congressman Thomas S. McMillan of the 1st congressional district, in office since 1925, defeated two Republican challengers.
