Finnian of Clonard – also Finian, Fionán or Fionnán in Irish; or Finianus and Finanus in its Latinised form (470–549) – was one of the early Irish monastic saints, who founded Clonard Abbey in modern-day County Meath. The Twelve Apostles of Ireland studied under him. Finnian of Clonard is considered one of the fathers of Irish monasticism.
