Donald Banfield (born 1937 or 1938) was a British man who disappeared from his home in Harrow, London in suspicious circumstances on 11 May 2001. His case is notable for being a rare case in which a murder conviction was secured without a body, and for this murder conviction being subsequently quashed on the grounds that a joint enterprise conviction in such a case where no body was found was not viable, even though the defence themselves said that the "likelihood" was that "one or other" of the women had murdered him.
