The anglicised spelling 'Arranmore' has no official status. Árainn Mhór (English name: Arranmore) is an island off the west coast of County Donegal in the north-west of Ulster, the northern province in Ireland. It is the county's largest inhabited island, with a population of 478 in 2022, but has had a gradually falling native population since the 1990s. Its main settlement is Leabgarrow. The island is part of the Gaeltacht, with most of the inhabitants speaking Ulster Irish. It is also known in English as Aran Island (not to be confused with the Aran Islands off Galway Bay or the Scottish Isle of Arran). In Irish it was traditionally called Árainn; the adjective mór (large) was added fairly recently. It was also sometimes called Árainn Uí Dhomhnaill, 'Aran of the O'Donnells'.
