The 1948 United States presidential election in Arizona took place on November 2, 1948, as part of the 1948 United States presidential election. State voters chose four representatives, or electors, to the Electoral College, who voted for president and vice president.
Arizona was won by incumbent President Harry S. Truman (D–Missouri), running with Senator Alben W. Barkley, with 53.79% of the popular vote, against Governor Thomas Dewey (R–New York), running with Governor Earl Warren, with 43.82% of the popular vote.
As of the 2024 presidential election, this is the last election in which Yavapai County voted for a Democratic presidential candidate. Maricopa County would not vote Democratic again until 2020. Coconino County would not vote Democratic again until 1992, Navajo County not until 1976, while Apache, Cochise, Mohave and Pima Counties would next vote Democratic for Lyndon Johnson in 1964.
This is also the last election where a candidate carried every county in the state and the last time a Democrat won the state with an outright majority. It is also the last time Arizona voted more Democratic than the nation as a whole. Arizona would vote Republican in every election thereafter except 1996 and 2020.
