809 Squadron (809 NAS), sometimes referred to as 809 Squadron, nicknamed Immortal, is a Fleet Air Arm (FAA) naval air squadron of the United Kingdom’s Royal Navy (RN). It currently operates the Lockheed Martin F-35B Lightning aircraft from RAF Marham, Norfolk, having recommissioned in 2023. The unit is jointly manned by both Royal Navy and Royal Air Force personnel and operates from Queen Elizabeth-class aircraft carriers.

It was first formed in 1941 and flew in the Soviet Union, the Mediterranean and the Far East during the Second World War. After active service during the Suez Crisis, 809 was disbanded in 1959. Reformed in 1963 to fly Blackburn Buccaneers, the squadron was disbanded briefly in 1965–66, and then again in 1978. A brief period during the Falklands War saw 809 reformed to bring Sea Harrier FRS.1 aircraft south to the UK task group and to fly from HMS Illustrious.
