Peter Kilkelly was an Irish Roman Catholic priest, who served as Bishop of Kilmacduagh from 1750 to 1783.
His family, Mac Giolla Cheallaigh, were a branch of the dynasty that once ruled Ui Fiachrach Aidhne, a kingdom occupying roughly the same land area as the diocese of Kilmacduagh.
A member of the Dominican Order, Kilkelly was appointed 22 June and consecrated 14 October 1744, and became Apostolic Administrator of Kilfenora when the two dioceses united in September 1750.
On his death, Kilfenora was united to the diocese of Kilmacduagh under Laurence Nihell (or Nihill), D.D., a native of Tulla, County Clare.
