John Kelly (Kelly of Killanne) (1773 – c. 25 June 1798) lived in the town of Killanne in the parish of Rathnure, west of Enniscorthy, in County Wexford in Ireland, and was a United Irish leader who fought in the Irish Rebellion of 1798. Kelly was obviously well known to rebel and loyalist alike during the short duration of the Wexford Rebellion but almost nothing is known of him outside this time. He was one of the leaders of the rebel victory at the Battle of Three Rocks which led to the capture of Wexford town but was later seriously wounded while leading a rebel column at the Battle of New Ross.
