Galway Bay (Irish: Loch Lurgan or Cuan na Gaillimhe) is a large bay (or sea lough) on the west coast of Ireland, between County Galway in the province of Connacht to the north and the Burren in County Clare in the province of Munster to the south. Galway city is located on the northeast side of the bay. It is about 50 kilometres (31 mi) long and from 10 kilometres (6.2 mi) to 30 kilometres (19 mi) in breadth. The Aran Islands (Oileáin Árann) are to the west across the entrance and there are numerous small islands within the bay. The approaches to the bay between the Aran Islands and the mainland are as follows; the North Sound (An Súnda ó Thuaidh) lies between Inishmore and Leitir Mealláin in Connemara; it was formerly known as Bealach Locha Lurgan in Irish. Gregory's Sound (Súnda Ghríoghóra) lies between Inishmore and Inishmaan; it was formerly known as Bealach na h-Áite. Foul Sound (An Súnda Salach) lies between Inishmaan and Inisheer; it was formerly known as Bealach na Fearbhaighe.
