About Us

The NCMF directly supports the National Cryptologic Museum (NCM), the first public museum in the U.S. Intelligence Community. We think you will agree it is truly a "museum like no other."

Located adjacent to the National Security Agency (NSA) in Maryland, the NCM houses a priceless collection of artifacts that represent our Nation's history in code making and code breaking, as well as a world class library of cryptologic media. The NCMF acquires the best artifacts for the NCM and supports new educational and interactive exhibits.

The NCMF provides exceptional cryptologic programs throughout the year, encourages young minds to explore cryptology and innovation through valued awards, and hosts educational, cryptology-related exhibits at various community events.

As part of the Foundation's partnership with NSA to build the Cyber Center for Education and Innovation - Home of the National Cryptologic Museum (CCEI-NCM), the NCMF also serves as a leader in the field of cybersecurity - striving to provide the best in educational resources and programs.

The NCMF and NCM share a joint three-fold mission to Educate, Stimulate, and Commemorate. Learn more about our MISSION.
