Perry Fellwock (born 1947) is a former National Security Agency (NSA) analyst and whistleblower who revealed the existence of the NSA and its worldwide covert surveillance network in an interview, using the pseudonym Winslow Peck, with Ramparts in 1971. At the time that Fellwock blew the whistle on ECHELON, the NSA was a nearly unknown organization and among the most secretive of the US intelligence agencies. Fellwock revealed that it had a significantly larger budget than the Central Intelligence Agency (CIA). Fellwock was motivated by Daniel Ellsberg's release of the Pentagon Papers. Today, Fellwock has been acknowledged as the first NSA whistleblower.

ECHELON is the name popularly given to the signals intelligence (SIGINT) collection and analysis network operated on behalf of the five signatory states (so called "Five Eyes" FVEY) to the UKUSA Security Agreement. According to information in a European Parliament document "On the existence of a global system for the interception of private and commercial communications (ECHELON interception system)", ECHELON was ostensibly created to monitor the military and diplomatic communications of the Soviet Union and its Eastern Bloc allies during the Cold War in the early 1960s.

Because of the Fellwock revelations, the U.S. Senate United States Senate Select Committee to Study Governmental Operations with Respect to Intelligence Activities ("Church Committee" as it was chaired by Frank Church) introduced successful legislation in 1973 to stop the NSA from spying on American citizens.
