A general election was held in the U.S. state of Wyoming on Tuesday, November 8, 1904. Two special elections were held: one for Governor and one for State Treasurer. In the gubernatorial election, acting Governor Fenimore Chatterton ran for re-election but was defeated for renomination at the Republican convention by Bryant B. Brooks, who won the subsequent special election over Democrat John E. Osborne. In the special election for State Treasurer, Republican William C. Irvine, who was appointed to the office by Governor Chatterton, successfully won re-election.
