Inishmore (Irish: Árainn [ˈaːɾˠən̠ʲ] , Árainn Mhór [ˈaːɾˠən̠ʲ woːɾ] or Inis Mór [ˈɪnʲɪʃ mˠoːɾ]) is the largest of the Aran Islands in Galway Bay, off the west coast of Ireland. With an area of 31 km2 (12 sq mi) and a population of 820 (as of 2016), it is the second-largest island off the Irish coast (after Achill) and most populous of the Aran Islands.

The island is in the Irish-speaking Gaeltacht and has a strong Irish culture. Much of the island is karst landscape and it has a wealth of ancient and medieval sites including Dún Aonghasa, described as "the most magnificent barbaric monument in Europe" by George Petrie. The island is a civil parish of the same name.
