John Gauden (1605 – 23 May 1662) was an English Bishop of Exeter then Bishop of Worcester and writer, and the reputed author of the important Royalist work Eikon Basilike.
He was born at Mayland, Essex, where his father was vicar of the parish, and educated at Bury St Edmunds school and at St John's College, Cambridge, where he took his M.A. degree in 1626. He married Elizabeth, daughter of Sir William Russell of Chippenham, Cambridgeshire, and was tutor at Oxford to two of his wife's brothers. He seems to have remained at Oxford until 1630, when he became vicar of Chippenham. His sympathies were at first with the parliamentary party. He was chaplain to Robert Rich, 2nd Earl of Warwick, and preached before the House of Commons in 1640.
In 1641 he was appointed to the rural deanery of Bocking. Apparently his views changed as the revolutionary tendency of the Presbyterian party became more pronounced, for in 1649 he addressed to Lord Fairfax A Religious and Loyal Protestation... against the proceedings of the parliament. Under the Commonwealth he faced both ways, keeping his ecclesiastical preferment, but publishing from time to time pamphlets on behalf of the Church of England. Whilst in Bocking he met William Juniper, the "Gosfield Seer" whom he first dismissed as a harmless fool. However, he was later impressed by prophecies made by Juniper, first that the King would be overthrown, and then that the monarchy would be restored.
