John Milbank (b. 1952) is an English Anglican theologian and was the Research Professor of Religion, Politics and Ethics at the University of Nottingham, where he also directs the Centre of Theology and Philosophy. Milbank previously taught at the University of Virginia and before that at the University of Cambridge and the University of Lancaster. He is also chairman of the trustees of the ResPublica think tank.

Milbank is known as the founder of the movement known as radical orthodoxy, which has attracted international attention in both religion and politics. His work crosses disciplinary boundaries, integrating subjects such as systematic theology, social theory, ethics, aesthetics, philosophy, political theory, and political theology. He first gained recognition after publishing Theology and Social Theory in 1990, which laid the theoretical foundations for the movement which later became known as radical orthodoxy. In recent years he has collaborated on three books with philosopher Slavoj Žižek and Creston Davis, entitled Theology and the Political: The New Debate (2005), The Monstrosity of Christ: Paradox or Dialectic (2009), and Paul's New Moment: Continental Philosophy and the Future of Christian Theology (2010). Milbank delivered the Stanton Lectures at Cambridge in 2011.
