12th Anti-Aircraft Brigade (12 AA Bde) was an air defence formation of the British Army during World War II. It specialised in providing anti-aircraft (AA) protection for forward airfields, for the Advanced Air Striking Force in the Battle of France and the Desert Air Force in the North African Campaign. It landed at Salerno in 1943 and fought through the Italian Campaign, its guns often engaging ground targets as well as aircraft. It was reformed postwar and continued for a few years in Anti-Aircraft Command.
