Ballymacnab (from Irish: Baile Mhic An Aba meaning "son of the abbot / McNab's town")[1] is a townland and village in County Armagh, Northern Ireland.

It is within the civil parish of Kilclooney, four miles south of the City of Armagh on the road towards Newtownhamilton.

[2] Local buildings and amenities include Saint Patrick's Roman Catholic Church, Foley primary school, and Ballymacnab Hall.

The majority Catholic population of Ballymacnab was reduced by emigration in the late nineteenth and early twentieth centuries.

A large stone marks the spot where it is claimed a large black bull landed after having been flung from neighbouring Armaghbreague Mountain by an angry Saint Patrick, after the same bull had knocked down the church he was building in Armaghbreague for the third consecutive night.
