Skreen (Irish: An Scrín, meaning 'the shrine') is a small village and parish in County Sligo, Ireland.

Besides his Columba biography, Adomnán is known for the Irish: Cáin Adomnáin the "Law of the Innocents", protecting women, children, and other non-combatants from being casualties of war.

In the life of St Farannan, published by Colgan, we are informed that Tibraide, lord of Tir Fhiachrach, bestowed on St Columba a place called Irish: Cnoc-na-maoile; but that it was subsequently called Irish: Scrín-Adhamhnain from a shrine that saint erected there.

Also in the parish are the considerable ruins of Ardnaglass Castle, originally a possession of the O'Dowds, then the MacSweeneys, and after the Cromwellian conquest the Joneses and the Blacks.

The Spiritual Life Institute, a Catholic order consisting of "apostolic hermits", also has a retreat centre in Skreen.
