The 1942 Arizona gubernatorial election took place on November 3, 1942. Incumbent Governor Sidney Preston Osborn ran for reelection, and easily defeated a challenge from former Governor Robert Taylor Jones in the Democratic primary, who Osborn also defeated in 1940. In a virtually identical race to 1940, Sidney Preston Osborn defeated Jerrie W. Lee in the general election, and was sworn into his second term as Governor on January 5, 1943.
