What Country Is Ireland? The Republic of Ireland

Ireland (or the Republic of Ireland, Poblacht na hÉireann) is a sovereign, independent country occupying five-sixths of the island of Ireland in the North Atlantic.

• Capital: Dublin (Baile Átha Cliath).
• Population: ~5.3 million (2024).
• EU member: Since 1973; eurozone since 1999.
• Government: Parliamentary democracy; President (ceremonial), Taoiseach (PM).

The remaining one-sixth of the island is Northern Ireland, part of the United Kingdom. The 1998 Good Friday Agreement governs cross-border relations.

So: "Ireland" = the Republic (country). "Northern Ireland" = UK region. The island = both.
