No. 304 (Land of Silesia) Polish Bomber Squadron (304 Dywizjon Bombowy "Ziemi Śląskiej im. Ks. Józefa Poniatowskiego") was a Polish World War II bomber unit. It fought alongside the Royal Air Force under their operational Command and operated from airbases in the United Kingdom, serving as a bomber unit in RAF Bomber Command, as an anti-submarine unit in RAF Coastal Command and as a transport unit in RAF Transport Command.

History
304 Squadron was created on 22 August 1940 and was declared ready for operations with Vickers Wellington medium bombers on 25 April 1941. On 7 May 1942 it was transferred to RAF Coastal Command along with the Wellingtons. Its last mission was on 30 May 1945, looking out for possible German submarines that would not surrender. On June 14, 1945 it was transferred to Transport Command, operating scheduled services with Warwick C.3s to Greece and Italy, but after April 1946 the Polish squadrons were restricted to flights within the UK. In May the squadron converted to Halifax Mk C.8 unarmed transports and was disbanded a few months later on 18 December 1946.
