The 1980 United States presidential election in Arizona took place on November 4, 1980. All fifty states and The District of Columbia were part of the 1980 United States presidential election. State voters chose six electors to the Electoral College, who voted for president and vice president. Reagan won every county except heavily unionized Greenlee, which would never vote Republican until 2000, in the process duplicating the state's 1972 county map. This stands as the last election when predominantly Native American Apache County has supported the Republican nominee.
