Royal Air Force Deanland or more simply RAF Deanland is a former Royal Air Force advanced landing ground located 4 miles (6.4 km) west of Hailsham, East Sussex and 13.4 miles (21.6 km) north east of Brighton, East Sussex, England

RAF Deanland was planned as an Advanced Landing Ground in order to provide support for the D-Day Landings on 6 June 1944, with construction started in Spring 1943. The first aircraft to take to the air on D-Day flew from RAF Deanland, providing top-cover over the OMAHA and GOLD landing beaches.

The airfield was heavily involved in the fight against the V-1 flying bombs (with 185 destroyed) and during D-Day in which it is believed to have been the home of the first Supermarine Spitfire squadron to provide air cover.

The landing ground was used by multiple units:

• No. 64 Squadron RAF
• No. 91 Squadron RAF
• No. 234 Squadron RAF
• No. 302 Polish Fighter Squadron
• No. 308 Polish Fighter Squadron
• No. 317 Polish Fighter Squadron
• No. 322 (Dutch) Squadron RAF
• No. 345 Squadron RAF
• No. 611 Squadron RAF
• No. 131 Airfield RAF
• No. 149 Airfield RAF
• No. 149 (Long Range Fighter) Wing RAF

Along with the following ground units at some point:

• No. 2750 Squadron RAF Regiment
• No. 2768 Squadron RAF Regiment

On 6 June 1994, an oak-tree was planted at the western end of the airfield entrance-road. This tree is a memorial to those pilots who flew from Deanland and died in operations.

The Airfield was dormant for a time, post-war, but the land came into the ownership of Richard Chandless, a farmer, who reactivated the site as an airfield in 1963. Richard operated his own aircraft, and he was for a number of years the main U.K. agent for Avions Pierre Robin demonstrating and selling new and used aircraft from Deanland. Richard invited a number of other aircraft owners to keep their machines at Deanland. During Chandless' time Deanland became a very active airfield, both day and night: lights were installed shortly after the runway was re-activated. It was used by a number of local business people, farmers and visitors to the area. With Glyndebourne Opera House close it was very normal to see both light aircraft and helicopters parked while their owners enjoyed the opera. In 1991 the airfield came into the ownership of Deanland Airfield LLP. In 2012 the airfield is still in use as a private airstrip.
