A Republican Party primary takes place on June 9, 2026, in South Carolina to determine which Republican candidate will run in the state's general election on November 3, 2026.

Candidate filing deadline	Primary election	General election
March 30, 2026	June 9, 2026	November 3, 2026

Heading into the election, the incumbent is Lindsey Graham (Republican), who was first elected in 2002.

A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. South Carolina utilizes an open primary system, in which registered voters do not have to be members of a party to vote in that party's primary. Voters must take an oath affirming that they have not voted in another party's primary.

For information about which offices are nominated via primary election, see this article.
