United States gubernatorial elections were held in 1931, in four states. Kentucky, Louisiana and Mississippi hold their gubernatorial elections in odd numbered years, every 4 years, preceding the United States presidential election year. New Jersey at this time held gubernatorial elections every 3 years. It would abandon this practice in 1949.
