Hugh de Lacy, Lord of Meath, 4th Baron Lacy (Anglo-Norman: Huge de Laci; before 1135 – 25 July 1186), was an Anglo-Norman landowner and royal office-holder. He had substantial land holdings in Herefordshire and Shropshire. Following his participation in the Anglo-Norman invasion of Ireland, he was granted, in 1172, the lands of the Kingdom of Meath by the Anglo-Norman King Henry II, but he had to gain control of them. The Lordship of Meath was then the most extensive liberty in Ireland.
