Saint Mo Ling (614–697), also named Moling Luachra,[1] was the second Bishop of Ferns in Ireland and has been said to be "one of the four great prophets of Erin".

[2] He founded a monastery at St Mullin's, County Carlow.

His feast day is 17 June.

[3][4] Traditions about him are preserved in two manuscripts, The Birth and Life of St. Moling, and the Borama, both of which expound on how he ended a cattle tributary imposed by the kings of Tara on the kings of Leighin, in retribution for an incident when the son of the king of Leighin went on a cattle raid to Clonfert, killing several princesses in the act.
