2016 United States presidential election in New Hampshire

The 2016 United States presidential election in New Hampshire was held on Tuesday, November 8, 2016, as part of the 2016 United States presidential election in which all 50 states plus the District of Columbia participated. New Hampshire voters chose electors to represent them in the Electoral College via a popular vote, pitting the Republican Party's nominee, businessman Donald Trump, and his running mate Indiana Governor Mike Pence, against the Democratic Party's nominee, former U.S. Secretary of State Hillary Clinton, and her running mate Virginia Senator Tim Kaine. New Hampshire has four electoral votes in the Electoral College.

Clinton won the state with 46.83% of the vote, while Trump lost with 46.46%, a 0.37% margin, or 2,736 votes. This result nonetheless made New Hampshire 1.73% more Republican than the nation-at-large, and remains the last time that New Hampshire has voted to the right of the national environment. This marked the second-closest margin percentage in the presidential election, behind only Michigan, and was Clinton's closest margin of victory of any state. This is the closest that a Republican nominee has come to carrying New Hampshire since 2000, when George W. Bush became the last Republican to carry the state. This also marked the first of only two times that a non-incumbent Republican won the White House without New Hampshire (along with 2024), and one of only three times overall (along with 2004 and 2024) in which any Republican won without carrying the state.
