List of Famous people named Ranulf

Ranulf de Blondeville, 6th Earl of Chester and 1st Earl of Lincoln (1170–1232), known in some references as the 4th Earl of Chester, was one of the "old school" of Anglo-Norman barons whose loyalty to the Angevin dynasty was consistent but contingent on the receipt of lucrative favours. He has been described as "almost the last relic of the great feudal aristocracy of the Conquest".

Ranulf de Glanvill was Chief Justiciar of England during the reign of King Henry II (1154–89) and was the probable author of Tractatus de legibus et consuetudinibus regni Anglie, the earliest treatise on the laws of England.

Ranulf II, 4th Earl of Chester (1099–1153), was an Anglo-Norman baron who inherited the honour of the palatine county of Chester upon the death of his father Ranulf le Meschin, 3rd Earl of Chester. He was descended from the Counts of Bessin in Normandy.

Ranulf le Meschin, 3rd Earl of Chester (1070−1129) was a Norman magnate based in northern and central England. Originating in Bessin in Normandy, Ranulf made his career in England thanks to his kinship with Hugh d'Avranches - the Earl of Chester, the patronage of kings William II Rufus and Henry I Beauclerc, and his marriage to Lucy, heiress of the Bolingbroke-Spalding estates in Lincolnshire.

Ranulf I (820–866) was a Count of Poitiers and Duke of Aquitaine. He is considered a possible son of Gerard, Count of Auvergne. Few details are known about Ranulf I, except that he died in 866 in Aquitaine from wounds received in the Battle of Brissarthe against the Vikings.

Ranulf II was Count of Poitou from 866 and Duke of Aquitaine from 887. On the death of Charles the Fat in 888, he styled himself King of Aquitaine and did so until 889 or his death, after which the title fell into abeyance.

Ranulf Flambard was a medieval Norman Bishop of Durham and an influential government minister of King William Rufus of England. Ranulf was the son of a priest of Bayeux, Normandy, and his nickname Flambard means incendiary or torch-bearer, and may have referred to his personality. He started his career under King William I of England, probably in the compilation of the Domesday Book, as well as being the keeper of the king's seal. On the death of William I, Ranulf chose to serve the new king of England, William Rufus.
