Ranulf de Blondeville, 6th Earl of Chester and 1st Earl of Lincoln (1170 – 26 October 1232), known in some references as the 4th Earl of Chester (in the second lineage of the title after the original family line was broken after the 2nd Earl), 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".
