Lough Neagh, sometimes Loch Neagh, is a freshwater lake in Northern Ireland. It is the largest lake in Northern Ireland, supplying 40% of its water; the biggest on the island of Ireland, the biggest by area in the United Kingdom, and the biggest by area in the British Isles. Its name comes from Irish: Loch nEachach, meaning "[[Lake of Eachaidh[[", although today it is usually spelt Loch nEathach in Gaelic.
