List of saints of Ireland
This is a list of the saints of Ireland, which attempts to give an overview of saints from Ireland or venerated in Ireland.
The vast majority of these saints lived during the 4th—10th centuries, a period in which Ireland was known as the "land of saints and scholars" — it produced many missionaries. The introduction of Christianity into Ireland was during the end of the 4th century. Its exact introduction is obscure, though the strict ascetic nature of monasticism in Ireland, derives from the Desert Fathers. Although there were some Christians in Ireland before him, Patrick from Britain played a significant role in its full Christianisation. Some of the most well known saints are the Twelve Apostles of Ireland and Brigit of Kildare.

- This column covers the religious houses which are strongly associated with the saint, e.g. because he or she was remembered or promoted as the founder and/or patron of a church. The modern name of the town or parish named after the church is given first, followed by the medieval Irish name where possible and by the county in which it is located today.
