1900 United States presidential election in New Hampshire

The 1900 United States presidential election in New Hampshire took place on November 6, 1900, as part of the 1900 United States presidential election. Voters chose four representatives, or electors to the Electoral College, who voted for president and vice president.

New Hampshire decisively voted for the Republican nominee, President William McKinley, over the Democratic nominee, former U.S. Representative and 1896 Democratic presidential nominee William Jennings Bryan. McKinley won New Hampshire by a margin of 20.91 points in this rematch of the 1896 presidential election. The return of economic prosperity and recent victory in the Spanish–American War helped McKinley to score a decisive victory.

Bryan had previous lost New Hampshire to McKinley four years earlier and would later lose the state again in 1908 to William Howard Taft.
