Sir Thomas Weyland (about 1230 – January 1298) was an English lawyer, administrator and landowner from Suffolk who rose to be Chief Justice of the Common Pleas under King Edward I but was removed for malpractice and exiled.
He spent an average of £150 a year on property while in office, and though much of the money may have come from the profits of his and his wife's landholdings or from private legal work, his relative lack of scruples makes it possible some came from corruption.
The killing may have been as a result of a drunken brawl, but it is probable it was part of bitter factional fighting between followers of the earl, of whom Weyland was one of the leading councillors.
He made his way to the Greyfriars house at Babwell on the outskirts of Bury St Edmunds, where he took the habit of the Franciscan order and received sanctuary.
Inheriting his father's lands, he too was knighted and married Mary, daughter of a major Suffolk landowner, Sir Richard Braose.
