Richard Mervyn Hare (21 March 1919 in Backwell, Somerset – 29 January 2002 in Ewelme, Oxfordshire) was an English moral philosopher who held the post of White's Professor of Moral Philosophy at the University of Oxford from 1966 until 1983. He subsequently taught for a number of years at the University of Florida. His meta-ethical theories were influential during the second half of the twentieth century.
Hare is best known for his development of prescriptivism as a meta-ethical theory. He believed that formal features of moral discourse could be used to show that correct moral reasoning will lead most agents to a form of preference utilitarianism.
Some of Hare's students, such as Brian McGuinness and Bernard Williams went on to become well-known philosophers. Peter Singer, known for his involvement with the animal liberation movement, was also a student of Hare's, and has explicitly adopted some elements of Hare's thought, though not his doctrine of universal prescriptivism.
