The Battery Maritime Building is a building at South Ferry on the southern tip of Manhattan Island in New York City. Located at 10 South Street, near the intersection with Whitehall Street, it contains an operational ferry terminal at ground level, as well as a hotel and event space on the upper stories. The ground story contains three ferry slips that are used for excursion trips and ferries to Governors Island, as well as commuter trips to Port Liberté, Jersey City. The upper stories contain the Cipriani South Street event space, operated by Cipriani S.A., and a 47-room hotel called Casa Cipriani.

South Ferry is at the southern tip of Manhattan in New York City and is the embarkation point for ferries to Staten Island and Governors Island. Battery Park, abutting South Ferry on the west, has docking areas for ferries to Liberty Island and Ellis Island. Its name is derived from the more southerly route of service of the historical South Ferry Company in comparison to the Fulton Ferry.
