This article contains the results of the 2016 Republican presidential primaries and caucuses, the processes by which the Republican Party selected delegates to attend the 2016 Republican National Convention from July 18–21. The series of primaries, caucuses, and state conventions culminated in the national convention, where the delegates cast their votes to formally select a candidate. A simple majority (1,237) of the total delegate votes (2,472) was required to become the party's nominee and was achieved by the nominee, businessman Donald Trump of New York.
The process began on March 23, 2015, when Texas Senator Ted Cruz became the first presidential candidate to announce his intentions to seek the office of United States President.
