Melanagh (from Irish: Meallanacht, meaning 'O'Mellons country') is an ancient Irish district in what is now north-eastern County Tyrone, Northern Ireland. Melanagh along with Tarraghter were once part of the barony of Loughinsholin until the Plantation of Ulster, which saw them merged with the barony of Mountjoy (modern-day barony of Dungannon Upper).
