The Boston Navy Yard, originally called the Charlestown Navy Yard and laterBoston Naval Shipyard, was one of the oldest shipbuilding facilities in the United States Navy. Established in 1801, under the last year of the Federalist Party administration of second President John Adams, (1735-1826, served 1797-1801) and the recent establishment of the new U.S. Department of the Navy in 1798. After 175 years of vaunted military service, it was officially closed as an active naval installation on 1 July 1974, and the 30-acre (12 ha) property was transferred to the National Park Service of the U.S. Department of the Interior to be part of Boston National Historical Park. Enough of the yard remains in operation to support the anchored/moored exhibiting as a historical museum, the "U.S.S. Constitution" ("Old Ironsides") of 1797, built as one of the original six heavy frigates for the revived American navy and oldest warship still commissioned in the United States Navy. The "U.S.S. Cassin Young (DD-793), a 1943 World War II-era Fletcher-class destroyer serving as a museum ship, is also berthed here, and there is also a dock which serves as a stop on the MBTA Boat water transport system. Among local people in the area and the National Park Service, it is still known as the Charlestown Navy Yard.

The South Boston Naval Annex was located along the waterfront in South Boston, Massachusetts.
