Ballymacnab Round Towers Gaelic Athletic Club (Irish: CLG na gCloigthithe, Baile Mhic an Aba) is a Gaelic Athletic Association club within Armagh GAA.

In 1925 a short-lived Ballymacnab team, Brian Ógs, affiliated to the Armagh GAA Junior League.

In the early 1930s a parish league was organised within Cill Chluana, out of which three clubs emerged over the following decades: Ballymacnab, Granemore and Clady.

After a hiatus, the Ballymacnab club was reformed as the Round Towers in 1967, and competed in Division IV of the Armagh League.

In 1975 the club purchased the playing field where it had long been based, and redeveloped the grounds as Páirc na nGael, officially opened in 1981.
