Lord Colvill was a title of nobility in the Peerage of England. The family rose through the Anglo-Norman aristocracy, holding lands in Lincolnshire, Yorkshire and Cambridgeshire, perhaps most notable being Weston in Cambridgeshire, subsequently called Weston-Colville. Walter de Colville of Castle Bytham in Lincolnshire was summoned in 1264 to a Parliament convened on behalf of Henry III of England by Simon de Montfort, who held the king captive. By later usage, this act is held to have ennobled the family as parliamentary barons, creating the title. Walter was captured by Prince Edward later that year and was forced to redeem his confiscated lands. The next two generations of the family were excluded from parliamentary summons and they were not again called until 1341/2, although the recipient, Robert de Colville, a great-grandson of Walter, had been attending Parliament as an unsummoned lord as early as 1331. The title fell into abeyance on the death of his son Robert at the age of 6 in 1370, his heirs being the descendants of two sisters of his great-grandfather, granddaughters of the Walter first summoned.
