The Republican National Convention is the presidential nominating convention of the Republican Party of the United States. Convened by the Republican National Committee, the stated purpose of the convocation is to nominate an official candidate in an upcoming U.S. presidential election, and to adopt the party platform and rules for the election cycle.

Like the Democratic National Convention, it signifies the end of a presidential primary season and the start of campaigning for a general election. In recent years, the nominee has been known well before the convention, leading many to oppose the convention as a mere public relations event and coronation.

Historically, the convention was the final determinant of the nomination, and often contentious as various factions of party insiders maneuvered to advance their candidates. Since the almost universal adoption of the primary election for selecting delegates in the last quarter of the 20th century, however, the convention's significance has diminished. The national party focuses on the convention as a unity point to bring together a party platform and state parties.
