The 2016 Republican National Convention, in which delegates of the United States Republican Party chose the party's nominees for president and vice president in the 2016 U.S. presidential election, was held July 18–21, 2016, at Quicken Loans Arena in Cleveland, Ohio. The event marked the third time Cleveland has hosted the Republican National Convention and the first since 1936. In addition to determining the party's national ticket, the convention ratified the party platform.

The 2016 United States presidential election was the 58th quadrennial presidential election, held on Tuesday, November 8, 2016. The Republican ticket, businessman Donald Trump and Indiana governor Mike Pence defeated the Democratic ticket of former secretary of state and First Lady of the United States Hillary Clinton and the junior senator from Virginia, Tim Kaine, in what was considered one of the biggest political upsets in American history. It was also the sixth presidential election in which both major party candidates were registered in the same home state; the others have been in 1860, 1904, 1920, 1940, and 1944.
