Royal Air Force Flowerdown or more simply RAF Flowerdown is a former Royal Air Force station located in Hampshire, England.

The Royal Flying Corps(RFC) Wireless School moved from Farnborough to Flowerdown, later RAF Flowerdown in 1918. The apprentice training school moved from Flowerdown to Cranwell in 1929[1] and the RNAS moved into Flowerdown which remained as a wireless station until 1956. It was never an airfield but it was bombed twice in one week.

In 1956 the site was taken over by GCHQ's Composite Signals Organisation as a large HF listening station. It closed in the late 1970s.

During the Second World War, Flowerdown was one of a number of listening stations around the country that fed information into Bletchley Park with staff working 12-hour shifts listening to Morse code which was then used to decipher the German codes.

In 1986 the site became the new depot for the Light Division when they moved from Peninsula Barracks, Winchester and was named Sir John Moore Barracks.[2] The barracks went on to become the home of the Army Training Regiment, Winchester.[3]
