While Mountcollins is now better known as a football club, their origins were in hurling. In 1888 Fr. Bernard O’ Mahony set up the Shamrocks Hurling Club whose colours were red with a green sash and a shamrock emblem.

The arrival of Fr. Byrne in the parish during the 1890's saw the formation of a football team and Mountcollins affiliated to the West Limerick GAA Board in 1926. The club provides football from U6’s right up to Junior A level.
