Baron de Clifford is a title in the Peerage of England. It was created in 1299 for Robert de Clifford (c.1274–1314), feudal baron of Clifford in Herefordshire, feudal baron of Skipton in Yorkshire and feudal baron of Appleby in Westmoreland. The title was created by writ, which means that it can descend through both male and female lines. The Norman family which later took the name de Clifford settled in England after the Norman Conquest of 1066 and was first seated in England at Clifford Castle in Herefordshire. The first Baron served as Earl Marshal of England but was killed at the Battle of Bannockburn in 1314. His 8th generation descendant the 11th Baron, was created Earl of Cumberland in 1525, whose grandson the 3rd Earl was a noted naval commander. On the latter's death in 1605, the earldom passed to his younger brother, the 4th Earl.
