The 1920 United States House of Representatives elections in South Carolina were held on November 2, 1920, to select seven Representatives for two-year terms from the state of South Carolina. Four incumbents were re-elected and all three open seats were retained by the Democrats. The composition of the state delegation thus remained solely Democratic.
Incumbent Democratic Congressman Richard S. Whaley of the 1st congressional district, in office since 1913, opted to retire. W. Turner Logan defeated F.F. Carroll in the Democratic primary and Republican challenger Saspartas in the general election.
Incumbent Democratic Congressman Frederick H. Dominick of the 3rd congressional district, in office since 1917, defeated W.W. Bradley in the Democratic primary and was unopposed in the general election.
Incumbent Democratic Congressman Edward C. Mann of the 7th congressional district, in office since 1919, was defeated in the Democratic primary by Hampton P. Fulmer. He defeated Republican challenger L.A. Hawkins in the general election.
