Aghaboe is a Roman Catholic parish in County Laois.
It is one of the parishes of the Roman Catholic Diocese of Ossory.
[2] According to Carrigan, in his 1905 history of the Roman Catholic Diocese of Ossory,[3] the Catholic parish comprised 19,610 acres at that time, having been reduced in area in 1855, when that part of the civil parish of Aghaboe which was situated in the Barony of Clandonnagh was removed—it was added to 100 acres of Kyledellig (presumably that part of Kildellig which, according to Lewis, was not part of the Catholic parish in 1837) to form the new Catholic parish of Borris-in-Ossary.
Carrigan also said that the part of the civil parish of Coolkerry which was in the Catholic parish of Aghaboe was the townlands of Middlemount and Coolacurragh.
In his 1837 Topographical Dictionary of Ireland, Lewis said that the Catholic parish of Aghaboe had four chapels, three of which were in the civil parish of Aghaboe, at Knockrea, Ballincolla, and Burros-in-Ossory.
