John Purvey (c. 1354 – c. 1414) was an English theologian, reformer, and disciple of John Wycliffe. He was born around 1354 in Lathbury, near Newport Pagnell in the county of Buckinghamshire, England. He was a great scholar, permitted to enter all priestly ranks on 13 March 1377, or 1378. It has been assumed by scholars that Purvey became acquainted with Wycliffe's ideas in Oxford. In around 1382, Purvey lived with Wycliffe at Lutterworth, Leicestershire, along with Nicholas of Hereford and John Aston, and became one of Wycliffe's disciples.
