The 1994 United States Senate election in Arizona was held November 8, 1994. Incumbent Democratic U.S. Senator Dennis DeConcini decided to retire instead of seeking a fourth term. Republican nominee Jon Kyl won the open seat, becoming the first Republican to win Arizona's Class 1 Senate seat since Paul Fannin in 1970. Democrats would not win this seat again, or any Senate race in the state, until Kyrsten Sinema's victory in 2018.
