The Washington Navy Yard 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 Historical Center, the Department of Naval History, the U.S. Navy Judge Advocate General's Corps, Naval Reactors, 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.

"The Man" is a slang phrase that may refer to the government or to some other authority in a position of power. In addition to this derogatory connotation, it may also serve as a term of respect and praise.

The phrase "the Man is keeping me down" is commonly used to describe oppression. The phrase "stick it to the Man" encourages resistance to authority, and essentially means "fight back" or "resist", either openly or via sabotage.

The earliest recorded use^{[citation needed]} of the term "the Man" in the American sense dates back to a letter written by a young Alexander Hamilton in September 1772, when he was 15. In a letter to his father James Hamilton, published in the Royal Dutch-American Gazette, he described the response of the Dutch governor of St. Croix to a hurricane that raked that island on August 31, 1772. "Our General has issued several very salutary and humane regulations and both in his publick and private measures, has shewn himself the Man." ^{[dubious – discuss]} In the Southern U.S. states, the phrase came to be applied to any man or any group in a position of authority, or to authority in the abstract. From about the 1950s the phrase was also an underworld code word for police, the warden of a prison or other law enforcement or penal authorities.
