Sir Robert de Herle was an English military commander who was Admiral of all the Fleets about England[1][2] and Lord Warden of the Cinque Ports during the mid-14th century.

He was the son of William de Herle (Chief Justice of the Court of Common Pleas intermittently between 1327–37 and one of the king's council until his death in 1364).

Robert was overlord at the Leicestershire village of Kirby Muxloe, but more significantly became one of Thomas, the earl of Warwick's most prominent retainers and was granted a life indenture at Wadborough.

During the 1340–50s all legal settlements in Warwickshire were subject to the goodwill of Thomas, earl of Warwick, who has been called 'the most powerful lay figure in the West Midlands', at the time.

He was appointed Commander-in-Chief of the English Navy from 2 December 1360 - 7 July 1364 with the title of Admiral of the Kings Southern, Northern and Western Fleets.
