The 1938 United States House of Representatives elections in South Carolina were held on November 8, 1938, to select six Representatives for two-year terms from the state of South Carolina. The primary elections were held on August 30 and the runoff elections were held two weeks later on September 13. Three incumbents were re-elected, but two incumbents were defeated in the Democratic primary. The three open seats were retained by the Democrats and the composition of the state delegation thus remained solely Democratic. 1st congressional district Incumbent Democratic Congressman Thomas S. McMillan of the 1st congressional district, in office since 1925, defeated A. Russell McGowan in the Democratic primary and Republican B.L. Hendrix in the general election.

Mahon, Jr. of the 4th congressional district, in office since 1937, was defeated in the Democratic primary by Joseph R. Bryson who defeated Republican H.A. Costner in the general election. The first primary had the two candidates only separated by 8 votes so the South Carolina Democratic Party Executive Committee ordered a new race instead of a recount, which Bryson clearly won.
