All Ireland

As an attributive, All Ireland emphasises the entire island of Ireland, as opposed to either the Republic of Ireland or Northern Ireland. In Irish Republicanism, the expression 32-county is often used instead: 32 as distinct from the 26 counties of the Republic and the remaining 6 of Northern Ireland.

"All-Ireland" is often used as an abbreviation of All-Ireland Championship, held by sports organised on All-Ireland basis. In particular:
* All-Ireland Senior Football Championship in Gaelic football
* All-Ireland Senior Hurling Championship in Hurling

Many sports are organised on an All-Ireland basis, for example basketball, boxing, cricket, curling, Gaelic football, golf, field hockey, horse racing, hurling, rugby league and rugby union. A notable exception is soccer.

Similarly, the term may be used in reference to annual competitions in certain traditional music and art forms:
* All-Ireland Fleadh in Irish music (see Fleadh Cheoil)
* All-Ireland Feis in Irish dance
* List of All-Ireland Champions in Traditional Irish music

It is also used in the title Primate of All Ireland, the senior clergyman in each of the Roman Catholic Church and the Church of Ireland:
* Archbishops of Armagh - Primate of All Ireland (Catholic)
* Archbishops of Armagh - Primate of All Ireland (Church of Ireland)
