The National Cryptologic Museum (NCM) is an American museum of cryptologic history that is affiliated with the National Security Agency (NSA). The first public museum in the U.S. Intelligence Community, it is located in the former Colony Seven Motel, two blocks from the NSA headquarters at Fort George G. Meade.

The NCM collection contains thousands of artifacts, including numerous working World War II German Enigma machines (two of them are available for visitors to try out), and a Navy Bombe used to break it. Displays discuss the history of American cryptology and the people, machines, techniques, and locations concerned.

Next to the museum is the National Vigilance Park (NVP), where three reconnaissance aircraft are on display. NCM and NVP are open to the public and admission is free.
