The 1984 United States presidential election in California took place on November 6, 1984, as part of the 1984 United States presidential election. State voters chose 47 representatives, or electors, to the Electoral College, who voted for president and vice president. California voted for the Republican incumbent and former California Governor, Ronald Reagan, in a landslide over the Democratic challenger, former Minnesota Senator and Vice President Walter Mondale. Reagan easily won his home state with a comfortable 16.24% margin and carried all but five counties. Despite this, California's margin was 1.97% more Democratic than the nation as a whole.
As of the 2024 presidential election, this is the last time a Republican carried the following California counties in a presidential election: Contra Costa, Humboldt, Los Angeles, Mendocino, San Mateo, Santa Clara, Solano and Sonoma. Mondale flipped Marin and Santa Cruz Counties.
Democratic primary Jesse Jackson's voters were 50% black, 38% white, 7% Hispanic, and 5% were members of other groups. Massachusetts was the only state where black voters composed a smaller percentage of his supporters.
