Bầu cử tổng thống Hoa Kỳ tại New Jersey năm 1804

A presidential election was held in New Jersey on November 6 and 7, 1804, as part of the 1804 United States presidential election. The Democratic-Republican Party's ticket of incumbent president Thomas Jefferson and former New York governor George Clinton was elected virtually without opposition.

Jefferson won the national election in a landslide over the de facto Federalist candidate, Charles Cotesworth Pinckney. Although a clandestine gathering of Federalist members of Congress had nominated Pinckney in February, in states where electors were chosen by popular vote, the Federalist ticket was formally unpledged. The New Jersey Federalist Party did not formally nominate electors, but a few Federalists received votes as write-in candidates.
