Woodrow Wilson Democratic Warren G. Harding Republican The 1920 United States presidential election in New Jersey took place on November 2, 1920.

New Jersey was won in a landslide by the Republican nominees, Senator Warren G. Harding of Ohio and his running mate Governor Calvin Coolidge of Massachusetts.

Harding and Coolidge defeated the Democratic nominees, Governor James M. Cox of Ohio and his running mate Assistant Secretary of the Navy Franklin D. Roosevelt of New York.

Like much of the Northeast, New Jersey in this era was a staunchly Republican state, having not given a majority of the vote to a Democratic presidential candidate since 1892.

With the deeply unpopular Democratic administration of Woodrow Wilson as the backdrop for the 1920 campaign, Warren G. Harding promised a "return to normalcy" that appealed to many voters, while Cox was tied to the policies of the Wilson administration.
