No. 459 Squadron RAAF was a Royal Australian Air Force squadron that operated during World War II. It was formed in early 1942 and served as a maritime patrol and bomber unit in the Mediterranean theatre until early 1945, operating mainly Lockheed Hudson aircraft. In early 1945, the squadron was transferred to the United Kingdom with the intention of being transferred to RAF Coastal Command and converting to Vickers Wellington bombers; however, due to a series of delays the conversion was not completed and the squadron was disbanded in April 1945.
