The Thorp street drill hall is a former military installation in Birmingham, England.

The building was designed by Frank Barlow Osborn as the headquarters of the 1st Volunteer Battalion, The Royal Warwickshire Regiment and was completed in 1881.

[2] The two battalions were mobilised at the drill hall in August 1914 before being deployed to the Western Front.

[2] Following a re-organisation in the Royal Artillery, 580 (The Royal Warwickshire Regiment) Light Anti-Aircraft Regiment Royal Artillery was formed at the Thorp Street drill hall in 1947[4] and, following a further amalgamation, 442 Light Anti-Aircraft Regiment, Royal Artillery was formed there in 1955.

[2] The regiment was broken up in 1961;[2] the drill hall was subsequently decommissioned and substantially demolished and the former frontage now forms the entrance to a car park,[5] in what is now the city's Gay Quarter.
