The National Museum of Computing is a museum in the United Kingdom dedicated to collecting and restoring historic computer systems.^[1] The museum is based in rented premises at Bletchley Park in Milton Keynes, Buckinghamshire^[2] and opened in 2007. The building — Block H — was the first purpose-built computer centre in the world, hosting six Colossus computers by the end of World War II.

The museum houses a rebuilt Mark 2 Colossus computer alongside an exhibition of the most complex code cracking activities performed at the Park, along with examples of machines continuing the history of the development of computing from the 1940s to the present day. The museum has a policy of having as many of the exhibits as possible in full working order.

Although located on the Bletchley Park "campus", The National Museum of Computing is an entirely separate registered charity^[3] with its own fund-raising and separate entrance/ticketing. TNMOC receives no public funding and relies on the generosity of donors and supporters.
