Nun's Island (sometimes Nuns Island; ) is an island on the River Corrib in Galway city, and an electoral division, close to Galway Cathedral. It is the location of St Joseph's Patrician College ("The Bish"), Nuns Island Theatre, some buildings operated by the University of Galway, and the site of the former Nun's Island Distillery, and Galway Crystal. Its name derives from a former Poor Clares convent on the island, which was founded in 1649.
