Elizabeth De Clare (1295 – 1360) was the heiress to the lordships of Clare, Suffolk in England and Usk in Wales. She was the youngest of the three daughters of Gilbert de Clare, 6th Earl of Hertford and Joan of Acre, and sister of Gilbert de Clare, who later succeeded as the 7th Earl. Born in Acre, she is commonly referred to as Elizabeth de Burgh, due to her first marriage to John de Burgh. Her two successive husbands were Theobald II de Verdun (of the Butler family) and Roger D'Amory.
