The 2016 South Carolina Republican presidential primary took place on February 20 in the U.S. state of South Carolina, marking the Republican Party's third nominating contest in their series of presidential primaries ahead of the 2016 presidential election.

The Democratic Party held its Nevada caucuses on the same day, while their South Carolina primary would only take place a week later on February 27.

The states delegates are allocated in this way: 29 delegates are awarded to the winner of the primary; 3 delegates are awarded to the winner of each of the seven congressional districts.

Donald Trump demonstrated his strength over the other candidates, winning among Southern White Evangelical Christians.  Marco Rubio, who had the support of then-Governor Nikki Haley, managed second place due to his support among college graduates.

Following a poor result in the primary, Jeb Bush announced the suspension of his campaign.

Carly Fiorina, Mike Huckabee, and Rick Santorum participated in the undercard debate. Rand Paul was also invited to the undercard debate, but said, "I won't participate in anything that's not first tier because we have a first tier campaign." The candidates were introduced in order of their poll rankings. The first question was to assess the economy. The next questions asked Fiorina about the role of the US in the world, Santorum about the Iran deal, and Huckabee about the solution to Afghanistan's problems.
