Sir Hugh deWilloughby (1135–1205) was an English knight and nobleman in Medieval England.
Hugh deWillougby was the son of John de Willoughby who held the Lordship of Willoughby, and his wife of an unknown name.
He married Frethsand Cockerington, daughter of William de Cokerinton and Berta.
Despite Ralph de Willoughby being the older brother, he did not inherit his father's wealth, which indicates that he could have possibly been a bastard.
When his wife's father, William de Cokerinton died, Sir Hugh de Willoughby inherited the villages of Cumberworth and Thorpe.
