Hampstead Barracks is an Australian Army base in the Adelaide suburb of Greenacres, located about to the north of the Adelaide central business district. Situated on the corner of Hampstead and Muller Roads, it is only a small suburban base, sitting on less than 24 acres of land. The barracks is home to the Tom Derrick VC Soldiers' Club, which is named after Tom Derrick, a South Australian Victoria Cross recipient from the Second World War.
