The Ministry of Home Security was a British government department established in 1939 to direct national civil defence (primarily tasked with organising air raid precautions) during the Second World War.

It was headed by Sir John Anderson the Home Secretary and Minister of Home Security. The Ministry's responsibilities covered all central and regional civil defence organisations (such as air raid wardens, rescue squads, fire services, and the Women’s Voluntary Service).

It was also responsible for giving approval to local ARP schemes, and providing public shelters.

With the Allied victory in Europe, the Ministry of Home Security was disbanded in May 1945.
