The 2006 Arizona gubernatorial election was held on November 7, 2006. Incumbent Governor Janet Napolitano was reelected in a landslide. Napolitano's widespread popularity contributed to her easy reelection; her general approval rating in October 2006, one month before the election, was at 58%.

This was the last time until 2022 that a Democrat was elected governor of Arizona. It is also the last time that a Democrat swept every county in the state in a statewide election.
