Saint Mo Chutu mac Fínaill (died 14 May 639), also known as Mochuda, Carthach or Carthach the Younger (a name Latinized as Carthagus and Anglicized as Carthage), was abbot of Rahan, County Offaly and subsequently, founder and first abbot of Lismore (Irish Les Mór Mo Chutu), County Waterford. The saint's Life has come down in several Irish and Latin recensions, which appear to derive from a Latin original written in the 11th or 12th century. His feast day in the Irish martyrologies is 14 May, as well as in the Great Synaxaristes of the Eastern Orthodox Church.
