Peter Trevers, or Travers (died 1468) was an Irish barrister and judge of the fifteenth century.
He belonged to a family which had settled in County Meath in the thirteenth century. John de Tryvers, judge of the Court of Common Pleas (Ireland) c.1283-5, was a member of the same family. He may also have been a relative of Peter Treveris, a well-known printer who was working in London in the 1520s. The family is thought to have been Cornish in origin: the most usual spelling of the name is Treffry. In 1460 Michael Trevers, possibly a relative of Peter, was given liberty by the Parliament of Ireland to enter on lands at Dubber and Coolock, north of Dublin city, in satisfaction of a debt owed to him by Piers de Coolock. In 1461 Peter granted the manor of Esker, near Lucan, Dublin, a royal property leased to favoured servants of the Crown, to John Trevers, possibly his brother or cousin, for Peter's lifetime.
