No. 334 (Norwegian) Squadron was a Royal Air Force aircraft squadron that operated after the Second World War. Established after V-E Day, it soon became 334 Squadron of the Royal Norwegian Air Force.

The squadron was formed on 26 May 1945 at RAF Banff, Scotland from B Flight of 333 Squadron. The squadron operated the de Havilland Mosquito on anti-shipping sorties and other operations along the Norwegian coast. Within a few weeks it had moved to Gardermoen and control was handed over to the Royal Norwegian Air Force on 21 November 1945.
