All-Ireland

The Four Provinces Flag of Ireland contains the flags of Ireland's four traditional constituent provinces: (clockwise, from the top left) Munster, Connacht, Leinster, and Ulster

All-Ireland (sometimes All-Island) refers to all of Ireland, as opposed to the separate jurisdictions of the Republic of Ireland and Northern Ireland. "All-Ireland" is most frequently used to refer to sporting teams or events for the entire island, but also has related meanings in politics and religion.
