The 2004 United States presidential election in New Jersey took place on November 2, 2004, and was part of the 2004 United States presidential election. Voters chose 15 representatives, or electors to the Electoral College, who voted for president and vice president.

New Jersey was won by Democratic nominee John Kerry by a 6.68% margin of victory. Prior to the election, most news organizations considered it as a state Kerry would win, or a blue state. Due to the impact of the September 11, 2001 attacks, however, and Governor James McGreevey's resignation amidst scandal, the state was considered a potentially closer than usual race. Polls showed Senator John F. Kerry with a slim lead throughout the campaign and the Republicans invested some campaign funds in the state. In the end, Kerry carried New Jersey by a comfortable margin, albeit narrower than usual for a 21st-century Democrat.

This remains the only election since 1880 in which the Republican nominee won the popular vote without New Jersey, and the only time it voted for the popular vote loser since 1976. As of the 2020 presidential election^[update], this is the last election in which the Democratic margin of victory was in single digits, or that the Republican won Somerset County.
