Eoghan Ua Cathain

Eoghan Ua Cathain (died 980) was Abbot of Clonfert.

Surnames had come into use in Ireland from about the 920's, and the prefix Ua (later Ó) may indicate that Eoghan was among the first to use the surname Ua Cathain in the west of Ireland.

There is a gap of sixty-six years between recorded abbots, rendering the exact succession between Aedh and Eoghan uncertain.
