Guy de Beauchamp, 10th Earl of Warwick (c. 1272 – 12 August 1315) was an English magnate, and one of the principal opponents of King Edward II and his favourite, Piers Gaveston. Guy was the son of William de Beauchamp, the first Beauchamp earl of Warwick, and succeeded his father in 1298. He distinguished himself at the Battle of Falkirk and subsequently, as a capable servant of the crown under King Edward I.

After the succession of Edward II in 1307, however, he soon fell out with the new king and the king's favourite, Piers Gaveston.[2] Warwick was one of the main architects behind the Ordinances of 1311, that limited the powers of the king and banished Gaveston into exile.
