The Air Defence of Great Britain (ADGB) was a Royal Air Force (RAF) command comprising substantial army and RAF elements responsible for the air defence of the British Isles. It lasted from 1925, following recommendations that the RAF take control of metropolitan air defence, until 1936 when it became RAF Fighter Command.

The ADGB was created as a command in 1925 as a result of the 1923 recommendation of the Steel–Bartholomew Committee, including their recommendation to transfer responsibility for home air defence from the War Office to the Air Ministry.[1] It main initial elements were:
ADGB was organised into three defensive zones:
In 1936, ADGB was abolished; the Bombing Area becoming Bomber Command and the Fighting Area becoming Fighter Command and remaining responsible for the ADGB function.[4][5][6] The OAZ was abolished and the AFZ expanded. The guns from the OAZ were used for port and base defence and were added to the London defences. The changing threat meant that AA defences were needed for many more potential targets in the British Isles, notably industries important for war production. The AA component became the 1st Anti-Aircraft Division and in 1937 the 2nd Anti-Aircraft Division was formed to defend the Midlands, with Anti-Aircraft Command created to replace the previous Army arrangements.[7]
In 1937, light AA guns were added, the RAF's view that small-calibre artillery were unsuitable having been finally overturned. In 1940, searchlights were transferred from the Royal Engineers to the Royal Artillery. Unrotated Projectile (rocket) batteries were deployed at the beginning of the war. At its peak from 1941–1942, AA Command comprised I, II and III Anti-Aircraft Corps with twelve AA divisions, comprising several hundred regiments. GOC-in-C AA Command for most of the war was General Sir Frederick Pile, the equal in rank of his 'superior' AOC-in-C Fighter Command.[8]
ADGB was resurrected in 1943 for the rump of Fighter Command defending the United Kingdom after the formation of the RAF Second Tactical Air Force in 1943 and AA Command.[9] It was Fighter Command in all but name, and this was finally reflected in 1944 with a return to the previous name.[10]
