The Washington Navy Yard (WNY) is the former shipyard and ordnance plant of the United States Navy in Southeast Washington, D.C. It is the oldest shore establishment of the U.S. Navy.

The Yard currently serves as a ceremonial and administrative center for the U.S. Navy, home to the Chief of Naval Operations, and is headquarters for the Naval Sea Systems Command, Naval Reactors, Naval Facilities Engineering Command, Naval Historical Center, the Department of Naval History, the U.S. Navy Judge Advocate General's Corps, Marine Corps Institute, the United States Navy Band, and other more classified facilities.

In 1998, the yard was listed as a Superfund site due to environmental contamination.

The history of the yard can be divided into its military history and cultural and scientific history.

The land was purchased under an Act of Congress on July 23, 1799. The Washington Navy Yard was established on October 2, 1799, the date the property was transferred to the Navy. It is the oldest shore establishment of the U.S. Navy. The Yard was built under the direction of Benjamin Stoddert, the first Secretary of the Navy, under the supervision of the Yard's first commandant, Commodore Thomas Tingey, who served in that capacity for 29 years.
