The 1990–91 Arizona gubernatorial election took place on November 6, 1990, for the post of Governor of Arizona. Incumbent Democratic Governor Rose Mofford declined to run for a full term. Republican Fife Symington defeated the Democratic nominee and Mayor of Phoenix Terry Goddard. Because no candidate received a majority of votes, a runoff election was held later on February 26, 1991, which Symington also won. This is the only election where Arizona used a runoff election.
Evan Mecham, a former governor who was removed from office in 1988 upon being convicted in his impeachment trial, unsuccessfully ran for another term in the Republican primary.
