Boetius Egan (Irish: Baothnalach Mac Aodhagáin; 1734–1798) was a Roman Catholic Archbishop of Tuam in County Galway, Ireland. Egan was born near Tuam, Ireland, to a family owning large estates in the County Galway. His family was reduced in position and means, and British Penal Laws made it then difficult for an Irish Catholic to receive Catholic education at home. At some point, he went to France to be trained as a priest. Egan attended the College of Bordeaux, there, which had been founded by Irish exiles and endowed by queen Anne in the seventeenth century.
