Martin Clive Warner SSC (born 24 December 1958)[2] is an Anglican bishop in England.

He then trained for ordination at St Stephen's House, Oxford, later earning a Doctor of Philosophy (PhD) degree at the University of Durham.

[11] In a compromise by John Sentamu, Archbishop of York, to whom the candidate professed canonical obedience, Warner officiated as principal celebrant in the laying-on of hands and Eucharist for the episcopal consecration of Philip North as suffragan Bishop of Burnley at York Minster on 2 February 2015 (Feast of Candlemas).

[...] Without seeking to diminish the value of many committed same-sex relationships, for which there is much to give thanks, we find ourselves constrained by what we sincerely believe the Scriptures teach which cannot be set aside.

[17]He voted against introducing "standalone services for same-sex couples" on a trial basis during a meeting of the General Synod in November 2023; the motion passed.
