The United States Senate election in California of 1940 was held on November 5, 1940. Incumbent Republican Senator Hiram Johnson was re-elected to his fifth term in office, though he would die in office in 1945.
By cross-filing and winning the Democratic and Progressive primaries, Johnson eliminated his strongest competition and handily won the general election with only nominal opposition from the Prohibition Party.
