The 1948 United States presidential election in California took place on November 2, 1948, as part of the 1948 United States presidential election. State voters chose 25 representatives, or electors, to the Electoral College, who voted for president and vice president.

California narrowly voted for the Democratic incumbent, Harry S. Truman, over the Republican challenger, New York Governor Thomas E. Dewey, even though Dewey's running mate was California Governor Earl Warren. California was the tipping-point state for Truman's victory.

The Progressive Party submitted 464,000 signatures, greater than the 275,970 required, from all but one of California's counties a month before the deadline. The final signature amount submitted was 482,781 with around 295,000 validated.^[2]
