Hugh de Mortimer (1117 – 26 February 1180/81) was a Norman English medieval lord.
During the Anarchy of King Stephen's reign, Mortimer was an ardent royalist[clarification needed] until at least 1148.
Hugh was one of the Barons who objected to Henry II's demand for the return of Royal castles in 1155.
Henry II launched a campaign in May 1155 against Hugh, simultaneously besieging his three principal castles of Wigmore, Bridgnorth and Cleobury.
Hugh may have died 26 Feb 1180/81 in Cleobury Mortimer, Shropshire, England, and was buried at Wigmore.
