Incumbent Republican Congressman Robert B. Elliott of the 3rd congressional district, in office since 1871, resigned in 1874 so that he could return to South Carolina and stem the massive corruption on the part of the state Republican Party. A special election was called to be held simultaneously with the regular election. Lewis C. Carpenter was nominated by the Republicans and was unopposed in the special election.
