Thomas Curwen (1415–1486/1487)[1] was a 15th-century sheriff of Cumberland. He was son of William Curwen and Elizabeth, daughter of John Huddleston of Millom Castle.[2] He held numerous offices around the region, including elector of the county (at which election he himself was elected), escheator and on various commissions. He was knighted in 1449.[1] He was a supporter of Henry Percy, 2nd Earl of Northumberland in Westmorland in the 1450s[3] during the Percy–Neville feud, although he made his peace when the Yorkist Edward IV took the throne in 1461.[4] When Edward's brother Richard took the throne in 1483, Curwen was appointed to each of his Cumberland commissions, although, as the parliamentary historian Josiah Wedgwood notes, "he must have been a very old man".[1]
