The 2018 United States House of Representatives elections in South Carolina were held on November 6, 2018, to elect the seven U.S. representatives from the state of South Carolina, one from each of the state's seven congressional districts. The elections coincided with a gubernatorial election, as well as other elections to the House of Representatives, elections to the United States Senate and various state and local elections.
This was the first time that the Democrats picked up a seat in South Carolina since 1986. The state congressional delegation changed from 6–1 for Republicans to 5–2 for Republicans. This is the only time since 2008 that Democrats had won more than one U.S. House seat in South Carolina.

### Republican primary

## District 5

The 5th district is located in northern South Carolina. The incumbent was Republican Ralph Norman, who had represented the district since 2017.

The primaries were held on June 12, 2018. Incumbent Ralph Norman was unopposed for the Republican nomination.

### Democratic primary

Special election candidate and former Goldman Sachs employee Parnell had the most fundraising of the four Democratic candidates as of June 9.

However, he refused to drop out of the race, and won the primary with 60% of the vote.
