Bầu cử tổng thống Hoa Kỳ tại New York năm 1984

The 1984 United States presidential election in New York took place on November 6, 1984, as part of the 1984 United States presidential election. All 50 States and the District of Columbia participated in this election. Voters in New York chose 36 representatives, or electors to the Electoral College, who selected president and vice president.

New York was won by Ronald Reagan with 53.84% of the popular vote over Walter Mondale with 45.83%, a victory margin of 8.01%. This made New York about 10% more Democratic than the nation overall. This was the third election since the Civil War (the first two being 1952 and 1956), in which New York voted less Democratic than neighboring Pennsylvania.

The county results indicate a then-typical split between New York's rural upstate and the large suburban counties around New York City, on the one hand, and the urban centers of New York City, Buffalo, and Albany, on the other. While Mondale carried the four most heavily populated boroughs of New York City with nearly 63% of the vote, the strong Republican performance across most of the upstate as well as in the heavily populated suburban counties of Nassau, Suffolk, and Westchester was able to secure the state's electoral votes for Reagan.
