Fulton Ferry describes a prominent ferry line crossing the East River between downtown Manhattan and Brooklyn, New York.

Fulton Ferry also describes the locations of this ferry's terminal at both landings, as was common practice.

Though there had been boats and sail ferries calling at these locations since the 18th century, the inauguration of Robert Fulton's steamboat ferry service in 1814 established his name on the ferry service, which revolutionized travel between the then City of New York on Manhattan Island and the Village of Brooklyn and the rest of Long Island.

The opening of the New York and Brooklyn Bridge in 1883 assured the decline of this and other ferries on the East River. Fulton Ferry service ended in 1924.

The major thoroughfares leading to the Fulton Ferry from both landings were (and are) named Fulton Street; see Fulton Street (Manhattan) and Fulton Street (Brooklyn).

The BMT Fulton Street Line and Old Main Line elevated railways both ended at the Brooklyn side of the ferry, but were later moved with the majority of trips using the Brooklyn Bridge.
