John Oliver (1601–1661) was an English royalist churchman, President of Magdalen College, Oxford, and Dean of Worcester.
He was born in Kent, and matriculated from Merton College, Oxford, on 26 January 1616.
He was tutor to Edward Hyde, when he was at Oxford, became vice-president of his college in 1634, held several livings and was made canon of Winchester in 1638, chaplain to William Laud in 1640.
In 1643 he took refuge after the unsuccessful royalist rising near Tonbridge with Dr. Buckner, who had been a tutor at Magdalen.
There he found Henry Hammond, who had a price on his head, and was escaping in disguise.
