The Minister of Supply was the minister in the British Government responsible for the Ministry of Supply, which existed to co-ordinate the supply of equipment to the national armed forces. The position was campaigned for by many sceptics of the foreign policy of the National Government in the 1930s before ultimately being created in 1939.

The Minister of Aircraft Production was, from 1940 to 1945, the British government minister at the Ministry of Aircraft Production, one of the specialised supply ministries set up by the British Government during World War II. It was responsible for aircraft production for the British forces, primarily the Royal Air Force, but also the Fleet Air Arm.
