The titles Baron Beauchamp and Viscount Beauchamp have been created several times throughout English and British history. There is an extant Viscountcy of Beauchamp, held by the Seymour family, Marquesses of Hertford.
The name Beauchamp (French "beautiful/fair field"), Latinised to de Bello Campo ("from the beautiful field/fair field"), is borne by three of the most ancient Anglo-Norman families which settled in England during the Norman Conquest of 1066: Beauchamp of Worcestershire, of Somerset and of Bedfordshire. The surname was taken from their respective manors in Normandy and there is no evidence of any shared origin between the families of that name seated in those three separate counties. The Bedfordshire branch died out in the male line after only two generations. The heir of the Somerset branch was the powerful Seymour family, whilst the Worcestershire branch achieved the greatest power and prominence as Earls of Warwick.
