Éire is the Irish Gaelic name for "Ireland". Like its English counterpart, the term Éire is used for both the island of Ireland and the Republic of Ireland, the sovereign state which governs 85% of the island's landmass. The latter is distinct from Northern Ireland, which covers the remainder of the northeast of the island. The same name is also sometimes used in English.

Ireland is an island in the North Atlantic Ocean, in north-western Europe. It is separated from Great Britain to its east by the North Channel, the Irish Sea, and St George's Channel. Ireland is the second-largest island of the British Isles, the third-largest in Europe, and the twentieth-largest in the world.
