The 1888 South Carolina United States House of Representatives elections were held on November 6, 1888 to select seven Representatives for two-year terms from the state of South Carolina. All seven incumbents were re-elected and the composition of the state delegation remained solely Democratic.
Incumbent Democratic Congressman William Elliott of the 7th congressional district, in office since 1887, defeated Republican challenger Thomas E. Miller. However, Miller successfully contested the election in the Republican controlled House of Representatives and replaced Elliott in September 1890.
