The 1988 United States Senate election in Arizona took place on November 8, 1988. Incumbent Democratic U.S. Senator Dennis DeConcini was reelected to a third term, even as incumbent Republican Vice President George H. W Bush won the state for president on the same ballot. This was the last time until 2018 that Democrats won a U.S. Senate seat in Arizona.
