A Gaelic football team has existed in the area around from at least 1916, becoming a founding member of the first North Armagh League in 1917.

From this time up until 1953 Clonmore's participation in organised Gaelic football was sporadic due to the limited availability of players.

[citation needed] The club was reformed in 1966, and adopted the Kerry colours of green and gold, while the earlier Clonmore teams had played in Cavan's blue and white.

In 2019, two Clonmore players, Emma Conlon and Sarah Quigley, were called up to the Senior Armagh Ladies County team.

The teams play as Naomh Eoin and have competed well at various levels, providing a number of County minors and under-21s.
