There have been several British military hospitals formerly operated by the Royal Air Force (RAF) of the United Kingdom.
They were primarily identified by the designation Royal Air Force Hospital Nnnnn (where 'Nnnnn' is the geographic location name).
This would typically be shortened to RAF Hospital Nnnnn (typically on road signs, in an identical manner to all Royal Air Force stations, aerodromes, and other RAF sites), and would be abbreviated RAF(H) Nnnnn.
Note: the county or location is listed as per its period of operation; counties, and their boundaries may have been subsequently renamed, merged, or abolished.
