No. 461 Squadron was a Royal Australian Air Force maritime patrol squadron during World War II which operated under Royal Air Force control flying in Europe and over the Atlantic. The squadron was formed in 1942 and was disbanded in mid-1945, just after the end of the war in Europe. Personnel were drawn from many countries of the British Empire, although the majority were Australians. Throughout the war, the squadron was credited with destroying a total of six German U-boats, and operated mainly in the Bay of Biscay and Atlantic.
