United States gubernatorial elections were held in 1921, in two states.
Virginia holds its gubernatorial elections in odd numbered years, every 4 years, following the United States presidential election year.
In North Dakota, the first-ever gubernatorial recall election was held. Incumbent governor Lynn Frazier was the first American governor ever successfully recalled from office; there would not be another successful recall of a governor until California Governor Gray Davis was recalled in 2003.
This election marked Republican's largest gubernatorial extent in history, tying with Jim Justice's party switch in 2017.
