The United States presidential election, 1820 was held from 1 November to 6 December 1820. The election took place at the height of the Era of Good Feelings, and it was the last election in which the winning candidate ran unopposed, with Democratic-Republican Party incumbent president James Monroe winning re-election with 231 electoral votes. William Plumer, a faithless elector from New Hampshire, voted for John Quincy Adams instead.
