Peter de Valognes was a Norman noble who became great landowner in England following the Norman Conquest.
Between 1070 and 1076 Peter de Valognes was granted lands in the six counties of Hertfordshire, Cambridgeshire, Norfolk, Suffolk, Essex and Lincolnshire. In 1086 when the Domesday book was completed, Peter was sheriff of the counties of Essex and Hertfordshire and he farmed the boroughs of Havering and Hertford. Although Peter de Valognes made his caput in Benington in Hertfordshire, his most valuable lands were in Norfolk, the latter being a later grant at the forfeiture of Ralph de Guader after the revolt of the Earls in 1075.
Peter de Valognes was the founder of Binham Priory in North Norfolk in 1091, which was built on land given to him by William the Conqueror. The land on which the priory stands was, according to the Domesday Book, originally the property of a freeman named Esket.
Peter de Valognes married Albreda, the sister of Eudo the Dapifer. They had three children who were Robert de Valognes (born circa 1080), Roger de Valognes (Born circa 1080) and Muriel de Valognes (Born circa 1087)
