John Holyman (c. 1495 – 20 December 1558) was a Roman Catholic English prelate, Bishop of Bristol (1554–1558).
He obtained his degree of Bachelor of Canon Law in 1514 and his Doctorate in 1526.
After a short period at the parish of Colerne, Wiltshire, he was admitted as a Benedictine monk at the Abbey of Reading where he had a reputation for his preaching.
Holyman was appointed Rector of Hanborough, Oxfordshire in 1534 and in November 1554 he was consecrated Bishop of Bristol.
Holyman also took part in the trial of John Hooper, Bishop of Gloucester.
