The 1964 United States House of Representatives elections in South Carolina were held on November 3, 1964 to select six
Representatives for two-year terms from the state of
South Carolina. The
primary elections were held on June 9 and the
runoff elections were held two weeks later on June 23. All five incumbents who ran were re-elected and the open seat in the
5th congressional district was retained by the
Democrats. The composition of the state delegation thus remained solely Democratic.
Incumbent Democratic Congressman
Robert T. Ashmore of the
4th congressional district, in office since 1953, won the Democratic primary and was unopposed in the general election.
Incumbent Democratic Congressman
Robert W. Hemphill of the
5th congressional district, in office since 1957, opted to retire.
Thomas S. Gettys won the Democratic primary and defeated Republican challenger Robert M. Doster in the general election.
