1984 United States presidential election in Arizona

The 1984 United States presidential election in Arizona took place on November 6, 1984. All fifty states and the District of Columbia, were part of the 1984 United States presidential election. State voters chose seven electors to the Electoral College, which selected the President and Vice President of the United States. Arizona was won by incumbent United States President Ronald Reagan of California, who was running against former Vice President Walter Mondale of Minnesota. Reagan ran for a second time with incumbent Vice President and former C.I.A. Director George H. W. Bush of Texas, and Mondale ran with Representative Geraldine Ferraro of New York, the first major female candidate for the vice presidency.

The presidential election of 1984 was a very partisan election for Arizona, with just under 99% of the electorate voting for either the Democratic or Republican parties, and only four parties appearing on the ballot. Nearly every county in Arizona voted with majorities for Reagan, a particularly strong turnout even in this typically conservative-leaning state. Reagan's win in Arizona was largely the result of a lopsided 45% victory margin in Maricopa County, the state's most populated county and home to Phoenix. Mondale did best in predominantly Native American Apache County, which was typical of his gains vis-à-vis Jimmy Carter in Native American counties throughout the nation; Reagan thus became the first-ever Republican to win the White House without carrying this county. Mondale also won heavily unionized copper-mining Greenlee County; albeit his performance there was the worst by a Democrat since statehood.

Arizona weighed in for this election as sixteen points more Republican than the national average. Reagan won the election in Arizona with a decisive 34-point landslide. No Republican candidate has received as strong of support in the American West at large as Reagan did.
