William Tynbegh, or de Thinbegh (c.1370-1424) was an Irish lawyer who had a long and distinguished career as a judge, holding office as Chief Justice of all three of the courts of common law and as Lord High Treasurer of Ireland. His career is unusual both for the exceptionally young age at which he became a judge, and because left the Bench to become Attorney General for Ireland, but later returned to judicial office.

Sir William Hankford, also written Hankeford, of Annery in Devon, was an English lawyer who acted as Chief Justice of the King's Bench from 1413 until 1423.
