Robert Stewart of Irry (1598–1662) was an Irish rebel. A colonel in the army, he was a prominent figure in the Irish Rebellion of 1641 and afterwards defended against the Cromwellian conquest of Ireland as Governor of the Castles of Antrim and Toome. His home outside Stewartstown, County Tyrone - Irry, sometimes also spelt Eary - was later renamed Stuart Hall by his grandson, the 7th Baron Castle Stewart. He died at Roughan Castle.
