The Honourable Artillery Company Museum opened in 1987 in Armoury House, City Road, London, England.

It is associated with the Honourable Artillery Company, the oldest regiment in the British Army, which still maintains an active regiment as a core part of today's Army Reserve.

The museum was opened in 1987 when a large volume of archival material and militaria was sorted and put on display.

[2] The collection includes uniforms, armour, silver, medals and decorations, weapons, equipment and applied art.

The archives date from 1537 and are of particular interest for 17th- and 18th-century militia and City of London matters.
