South Carolina Cộng hòa bầu cử tổng thống sơ bộ năm 2024

The 2024 South Carolina Republican presidential primary was held on February 24, 2024, as part of the Republican Party primaries for the 2024 presidential election. 50 delegates to the 2024 Republican National Convention were allocated on a selection basis.

Held following the Iowa caucuses, the New Hampshire primary, the Nevada primary and caucuses, and the United States Virgin Islands caucuses, the South Carolina primary was the fifth Republican contest in which delegates were awarded to take place this election. South Carolina holds the "first in the South" presidential primary for both major parties.

Nikki Haley, who served as Governor of South Carolina from 2011 to 2017, announced her presidential candidacy in February 2023. Tim Scott, who has represented South Carolina in the U.S. Senate since 2013, entered the race with a campaign announcement in May 2023. He suspended his campaign on November 12, 2023 and endorsed Trump on January 19, 2024.

Immediately after polls closed at 7:00pm EST, multiple media outlets called the primary for Trump. Trump received the highest number of votes of any candidate for either party in the history of the South Carolina primaries, breaking the record previously held by George W. Bush in 2000.
