1956 United States presidential election in California

The 1956 United States presidential election in California took place in November 1956 as part of the 1956 United States presidential election. State voters chose 32 representatives, or electors, to the Electoral College, who voted for president and vice president. California voted for the Republican incumbent, Dwight D. Eisenhower (with incumbent vice president and California native Richard Nixon as his running mate), in a landslide over the Democratic challenger, former Illinois Governor Adlai Stevenson. However, Stevenson did improve his performance in California from four years previous. California's result was about 4.3% more Democratic than the nation-at-large.

As of the 2020 presidential election, this is the last presidential election in California where the Republican candidate won the counties of Alameda and San Francisco, both of which have become strongholds of the Democratic Party.
