The 32nd Arizona State Legislature, consisting of the Arizona State Senate and the Arizona House of Representatives, was constituted in Phoenix from January 1, 1975 to December 31, 1976, during the first two years of Raúl Héctor Castro's single term as Governor of Arizona. Both the Senate and the House membership remained constant at 30 and 60, respectively. The Democrats reversed the margin of control in the upper house, gaining an 18–12 edge in the senate, while they also made inroads in the Republican's majority in the house, although the Republicans still controlled the lower body with a 33–27 margin.
