The 1962 United States Senate election in Arizona took place on November 6, 1962. Incumbent Democratic U.S. Senator Carl Hayden ran for reelection to a seventh term, defeating Republican nominee State Senator Evan Mecham in the general election. Mecham became Governor of Arizona more than two decades later, and was subsequently impeached from office.
This would be Senator Carl Hayden's final run for U.S. Senate, he would be succeeded in office by former U.S. Senator Barry Goldwater in 1968.
State Senator Evan Mecham ran for U.S. Senate, and was challenged by political operative and strategist Stephen Shadegg. Shadegg, who had served as campaign manager for both Republican and Democratic candidates, had run at the urging of Senator Barry Goldwater, but Goldwater failed to officially endorse any candidate in the Republican primary. Shadegg later said that he was "terriby let down" by Goldwater's position of neutrality in the primary after Goldwater had urged Shadegg to seek the seat.
