Michael Graham (1898–1972) CMG OBE was a British fisheries scientist, author, and ecologist. He was the director of the Ministry of Agriculture, Fisheries and Food (United Kingdom) fisheries laboratory in Lowestoft (1945–1958), now known as the Centre for Environment, Fisheries and Aquaculture Science (Cefas). His classic book, The Fish Gate, published in 1943, paints a picture of the near-collapse of the British fishing industry through overfishing that occurred before both the First and the Second World Wars.
