Maurice Campbell Cornforth (1909 – 1980) was a British Marxist philosopher. Initially, he was in the early 1930s a follower of Wittgenstein, writing in the style of the analytic philosophy of the time. He later became in effect the official ideologist of the Communist Party of Great Britain.

He is noted for his attack on the aesthetic theories of Christopher Caudwell, and for his later partial engagement with the linguistic philosophy of Oxford origin of the 1940s and 1960s. He also wrote a defence of Marxism against Karl Popper's criticisms.
