The Knightbridge Professorship of Philosophy is the senior professorship in philosophy at the University of Cambridge.
One of the oldest professorships in Cambridge, the chair was founded in 1683 by John Knightbridge, fellow of Peterhouse.
Originally entitled the "Professorship of Moral Theology or Casuisticall Divinity", with the holder often known as simply the "Professor of Casuistry", the scope of the professorship was officially broadened from merely moral to general philosophy under its present name in 1965.
