No. 603 (City of Edinburgh) Squadron is a squadron of the Royal Auxiliary Air Force, based in Edinburgh, Scotland. On reforming on 1 October 1999, the primary role of 603 Squadron, was as a Survive to Operate squadron, as well as providing Force Protection.

603 Sqn re-roled to become a reserve RAF Police unit from 1 April 2013. The Squadron retains a squadron's complement of RAF Regiment as part of its overall contribution to Force Protection and it still operates from a magnificent Victorian Town Mansion close to Edinburgh's city centre, as it has since the Town Headquarters was bought for the squadron in 1925.

Queen Elizabeth II is the Honorary Air Commodore to the Squadron, with those duties routinely carried out by Air Marshal Sir David Walker.
