U.S. senator before election Henry F. Ashurst Democratic Elected U.S. Senator Ernest McFarland Democratic

The 1940 United States Senate elections in Arizona took place on November 5, 1940. Incumbent Democratic U.S. Senator Henry F. Ashurst ran for reelection to a sixth term, but was defeated in the Democratic primary to challenger Ernest McFarland.

The twenty-eight-year Democratic incumbent, Henry F. Ashurst, appeared to be unbeatable and did not launch an aggressive campaign to retain his seat. While Ashurst remained in Washington, D.C., McFarland canvassed the state, giving speeches on water issues and World War II in Europe. He defeated Ashurst in the primary and went on to win the general election, defeating Republican challenger Irving A. Jennings.
