The 1990 Wyoming gubernatorial election took place on November 6, 1990. Incumbent Democratic Governor Mike Sullivan ran for re-election. In the general election, he faced Republican nominee Mary Mead, a businesswoman and the daughter of former U.S. Senator and Governor Clifford Hansen. Owing to Sullivan's personal popularity, he won re-election over Mead in a landslide, marking the fifth straight Democratic victory in Wyoming's gubernatorial races, a streak that has yet to be broken by either party.
