Saint Iserninus (or Isernius) (c. 456 AD) was an early Christian missionary of Ireland who is associated with Saint Patrick and Saint Auxilius in establishing Christianity in the south of that island. More recent research associates him not with Patrick but with Palladius.Saint Iserninus is thought to have been a Briton or Irishman and is associated with the lands of the Uí Cheinnselaig in Leinster.
