The former Royal Air Force Station Dallachy, commonly known as RAF Dallachy, was a British Royal Air Force airbase situated east of Elgin, in Moray, Scotland. During World War II it was a fighter station, used by 18 Group Coastal Ops.
Opened in March 1943, it was originally used as a training station by the 14 (Pilot) Advanced Flying Unit, using Airspeed Oxfords. In September 1943, it was reorganized for operational use by several squadrons, including No. 144 Squadron RAF, No. 404 Squadron RCAF and No. 455 Squadron RAAF. Towards the end of 1944, it was reorganized again with No. 489 Squadron RNZAF, flying Beaufighters on shipping strikes, and No. 524 Squadron RAF with radar-equipped Wellingtons.
The airfield was closed in June 1945, becoming a Territorial Army training center until 1958.
A memorial now stands in the nearby village of Bogmoor to remember the soldiers who lost their lives in World War II.
