Primate of All Ireland is the title held by the Archbishop of Armagh. Both the Roman Catholic and Church of Ireland faiths in Ireland have an Archbishop of Armagh who serves as Primate of All Ireland.

The Catholic Archbishop of Armagh is Sean Brady, Archbishop of Armagh. The Church of Ireland Archbishop of Armagh is Robin Eames, Archbishop of Armagh.

Prior to the disestablishment of the Church of Ireland in 1871, the Church of Ireland Archbishop of Armagh was entitled to sit in the House of Lords as a Lord Spiritual, along with the other Archbishops in rotation.

Though the island of Ireland was partitioned by the Government of Ireland Act 1920 into two states now known as the Republic of Ireland and Northern Ireland, all major Irish religions are organised on an all-island basis. Within the Republic of Ireland, the senior bishop in both the Catholic and Church of Ireland faiths is the Archbishop of Dublin who is known as the Primate of Ireland.
