Body of Secrets: Anatomy of the Ultra-Secret National Security Agency is a book by James Bamford about the NSA and its operations.

It also covers the history of espionage in the United States from uses of the Fulton surface-to-air recovery system to retrieve personnel on Arctic Ocean drift stations to Operation Northwoods, a declassified US military plan that Bamford describes as a "secret and bloody war of terrorism against their own country in order to trick the American public into supporting an ill-conceived war they intended to launch against Cuba.
