John Devereux, 8th Baron Ferrers of Chartley

John Devereux, 8th Baron Ferrers of Chartley (1463 – 3 May 1501) was an English peer.

He was the eldest son and heir of Anne Ferrers, 7th Baroness Ferrers of Chartley by her husband and consort Walter Devereux, Lord Ferrers of Chartley.

His mother died of natural causes on 9 January 1468/9, but his father remained the jure uxoris Baron for the remainder of his life. John Devereux served as Justice of the Peace with his father in 1483 and 1484., and on 1 August 1483 they were assigned to assess and appoint collectors of the subsidies granted by Parliament from aliens in Herefordshire. His father died in the Battle of Bosworth Field (22 August 1485) fighting for Richard III of England under John Howard, 1st Duke of Norfolk. Richard III was killed in the battle and his opponent succeeded him as Henry VII of England causing the Devereux lands to be forfeited.

On 4 March 1485/6 John Devereux was granted special livery, without proof of age, of his mother's lands. He was summoned to Parliament on 1 September 1487 for the first time. At his second Parliament on 13 January 1488/9 his petition for reversal of his father's attainder and forfeiture was granted, and he was thereby able to inherit his father's lands. He would remain loyal to Henry VII for the rest of his life.
