The 1952 United States Senate election in California was held on November 4, 1952, concurrently with the 1952 U.S. presidential election as well as other elections to the United States Senate and House of Representatives and various state and local elections.

By cross-filing and winning the Democratic nomination, incumbent Republican Senator William F. Knowland was able to cruise to a general election victory with only nominal opposition.

Until 1988, this was the last time a nominee from either party won re-election to this seat.
