Edward Dillon (1739–1809) was an Irish clergyman who served as a Roman Catholic prelate in Ireland during the late 18th and early 19th centuries.

On 18 December 1791 Dillon presented a petition to the local revolutionary committee acknowledging French generosity but denying charges of partiality towards the royalist faction.

War between France and the Great Britain in 1793 brought an end to the immunity and the closure of the college.

Dillon returned to Ireland and appointed coadjutor bishop of the diocese of Kilmacduagh and Kilfenora on 21 January 1794, and the following year succeeded as the diocesan Bishop of Kilmacduagh and Kilfenora on 29 June 1795.

He was unpopular with both his flock and the ruling class; the former for his denouncements of the United Irishmen and the French revolution.
