704 Naval Air Squadron (704 NAS) was a Naval Air Squadron of the Royal Navy's Fleet Air Arm. It formed as a Operational Training Unit, at RNAS Zeals (HMS Hummingbird) in Wiltshire, in April 1945, operating with de Havilland Mosquito aircraft. The squadron later moved to RAF Thorney Island in West Sussex, in the September, and continued with de Havilland Mosquito conversion courses, however the squadron disbanded in December 1945.

Naval Operational Training Unit (1945)
On 11 April 1945, 704 Naval Air Squadron was formed at RNAS Zeals (HMS Hummingbird), located near the village of Zeals in Wiltshire, as a Naval Operational Training Unit, for the conversion of de Havilland Mosquito aircrew. The squadron was equipped with de Havilland Mosquito, a British twin-engined, multirole combat aircraft. It mainly operated with the FB.VI strike ("fighter-bomber") variant and also had a smaller number of T.III two-seat trainer versions.

On 20 June four of the aircraft were detached to 703 Naval Air Squadron which was operating at RAF Thorney Island, which was located on Thorney Island, West Sussex. The aircraft were utilised for development work in conjunction with the Royal Air Force’s Air-Sea Warfare Development Unit (ASWDU). The rest of 704 NAS relocated to RAF Thorney Island on 4 September and the detachment was incorporated back into the squadron. Three months later the squadron disbanded on 2 December 1945 when it was absorbed into 762 Naval Air Squadron, a Twin Engine Conversion Unit.
