United States gubernatorial elections were held on November 3, 2020, in 11 states and two territories. The previous gubernatorial elections for this group of states took place in 2016, except in New Hampshire and Vermont where governors only serve two-year terms. These two states elected their current governors in 2018. Nine state governors ran for reelection and all nine won, while Democrat Steve Bullock of Montana could not run again due to term limits and Republican Gary Herbert of Utah decided to retire at the end of his term.
