Colin Ewart Gunton (19 January 1941-6 May 2003) was a British systematic theologian. He made contributions to the doctrine of Creation and the doctrine of the trinity. He was Professor of Christian Doctrine at King's College London from 1984 and co-founder with Christoph Schwoebel of the Research Institute for Systematic Theology in 1988. Gunton was actively involved in the United Reformed Church in the United Kingdom where he had been a minister since 1972.
Gunton grew up in Nottingham, England. He first studied the Classics at Hertford College, Oxford and graduated with a B.A. in 1966, the same year he was married. He then began his study of theology, and a year later received an M.A. from Mansfield College, Oxford. He then began his doctoral work under the direction of Robert Jenson, which took six years because he began teaching two years into his doctoral program as he became Lecturer in Philosophy of Religion at King's College London in 1969. His dissertation was a study of the doctrine of God in the thought of Charles Hartshorne and Karl Barth, which was completed in 1973. He became an Associate Minister of the Brentwood United Reformed Church in 1975, a position which he held until his death.
