The 1932 United States Senate election in California was held on November 2, 1932. Incumbent Republican Senator Samuel Morgan Shortridge ran for a third term in office, but lost a highly competitive four-way Republican primary to Tallant Tubbs, who ran as a "wet" or anti-prohibition candidate.
In the general election, former Secretary of the Treasury and presidential candidate William Gibbs McAdoo won a three-way race against Tubbs and Prohibition candidate Robert P. Shuler, who received the most votes of any Prohibition candidate in United States history.
