Edward Wetenhall (1636–1713) was an English bishop of the Church of Ireland. His name is also spelled Wettenhall, Whetenhall, Whitnall, Withnoll, and Wythnall.
He was born at Lichfield on 7 October 1636. Educated at Westminster School under Richard Busby, he was admitted as a king's scholar in 1651, and went to Trinity College, Cambridge, as a foundation scholar. After graduating B.A. 1659–60, he migrated (1660) to Lincoln College, Oxford, of which he became chaplain, was incorporated B.A. 18 June, and graduated M.A. 10 July 1661.
He held the perpetual curacy of Combe Long, Oxfordshire, and the vicarage of St. Stephen's, near St Albans, Hertfordshire; on 11 June 1667 he was to a prebend at Exeter, holding with it the mastership (headmaster) of the blue-coat school. He graduated B.D. at Oxford 26 May 1669, and was incorporated B.D. at Cambridge 1670. Michael Boyle the younger, the Archbishop of Dublin, brought him over to Dublin in 1672, as master of the blue-coat school. He was made a Doctor of Divinity at Trinity College, Dublin, became curate of St. Werburgh's Church, and afterwards chantor of Christ Church. On the death (22 December 1678) of Edward Synge, bishop of Cork, Cloyne, and Ross, the sees were separated, and Wetenhall was made (14 February 1679) bishop of Cork and Ross, being consecrated 23 March 1679 in Christ Church, Dublin.
At his own cost he restored the episcopal residence at Cork. As one of the seven bishops who remained in Ireland during the troubles which began in 1688, he was exposed to much ill-usage at the hands of the partisans of James II. He was probably the author of an anonymous tract ‘The Case of the Irish Protestants in relation to … Allegiance to … King William and Queen Mary,’ 1691 (27 October 1690). He signed the episcopal letter of thanks (November 1692) to Thomas Firmin for his exertions in relief of the distressed Protestants of Ireland. Only one Irish prelate, William Sheridan (died 1716) of Kilmore and Ardagh, was deprived (1691) as a nonjuror. Wetenhall, who was translated as bishop of Kilmore and Ardagh on 18 April 1699, would not accept the preferment without trying to procure the restoration of Sheridan, to whose support he contributed. He restored the episcopal residence at Kilmore and rebuilt the cathedral at Ardagh (later demolished). He recovered lands belonging to the see, alienated by William Smith (d. 1698), his predecessor, but also sold a valuable wood of the see.
