The 1946 Wyoming gubernatorial election took place on November 5, 1946. Incumbent Democratic Governor Lester C. Hunt ran for re-election to a second term. Former Republican Governor Nels H. Smith, whom Hunt defeated in 1942, announced that he would challenge Hunt for re-election, but he was defeated the Republican primary by State Treasurer Earl Wright. In the general election, even though the Republican Party had a strong performance nationwide, Wyoming Democrats did well; Hunt defeated Wright by a wider margin than his 1942 victory as Democratic U.S. Senator Joseph C. O'Mahoney similarly won another term.
