List of loughs of Ireland


This is an alphabetical list of loughs on the island of Ireland. It also shows a table of the largest loughs. The word lough is pronounced like loch and comes from the Irish loch, meaning 'lake'.
According to the Environmental Protection Agency, there are an estimated 12,000 lakes in the Republic of Ireland, covering an area of more than 1,200 square kilometres. The largest lough, by area, in Ireland is Lough Neagh. Lough Corrib is the second largest, and is the largest in the Republic. The largest lough, by water volume, is Lough Neagh, with Lough Mask being the largest by volume in the Republic.
The list below contains only those loughs that are of geographic, geological, or historical importance and almost all of them are over a square kilometre in area. It includes loughs that are in Northern Ireland and the Republic of Ireland. Those partly or wholly within Northern Ireland are marked with an asterisk.
