The 1974 Arizona gubernatorial election took place on November 5, 1974. Incumbent Governor Jack Williams decided not to run for a fourth term as governor. Former United States Ambassador to BoliviaRaúl Héctor Castro, who was the Democratic nominee in 1970, won the Democratic nomination again in 1974, and narrowly won the general election, defeating Republican nominee Russell Williams by 0.85%. Castro was sworn into his first and only term as governor on January 6, 1975.
Prior to the election, there was a recall effort led by Cesar Chavez against incumbent Governor Jack Williams, with 180,000 signatures submitted. Many of the signatures were invalidated by the Attorney General Gary Nelson, but this eventually overturned. By the time this occurred, however, it was meaningless due to the close proximity of the 1974 gubernatorial election, and thus a recall election did not occur.
