The 1970 United States Senate election in Arizona took place on November 3, 1970. Incumbent Republican U.S. Senator Paul Fannin decided to run for reelection to a second term, running unopposed in the Republican primary. Fannin defeated Democratic nominee Sam Grossman in the general election. This was the last time until 1994 that Republicans won Arizona's Class 1 Senate Seat.
