William de Valence (died 13 June 1296), born Guillaume de Lusignan, was a French nobleman and knight who became important in English politics due to his relationship to King Henry III of England. He was heavily involved in the Second Barons' War, supporting the king and Prince Edward against the rebels led by Simon de Montfort. He took the name de Valence ("of Valence") after his birthplace, the Cistercian abbey of Valence, near Lusignan in Poitou.[1]
