Đảng Cộng hòa bầu cử tổng thống năm 1984

From February 20 to July 1, 1984, voters of the Republican Party chose its nominee for president in the 1984 United States presidential election. Incumbent President Ronald Reagan was again selected as the nominee through a series of primary elections and caucuses culminating in the 1984 Republican National Convention held from August 20 to August 23, 1984, in Dallas, Texas.

The primaries were uneventful as Reagan was virtually assured of the nomination by virtue of his popularity within the party. Thus, he faced only token opposition in the primary race. Ronald Reagan won in a landslide, winning every contest and garnering more than 6.4 million votes. Former Minnesota governor Harold Stassen opposed Reagan for the Republican nomination and criticized the President's foreign policy, the budget deficit, and the trade imbalance. Stassen earned less than 13,000 votes, merely 0.19% of the total votes cast. Ronald Reagan would go on to win the most Electoral votes achieved by any president in history in the general election of that year.
