The Gaelic Athletic Association has been part of life in Newmarket since the closing years of the 19th century.

That same year they played in the Cork Senior Football Championship, losing to eventual winners Collins Barracks.

Newmarket returned to the Cork Junior Football Championship final in 1950, losing out to Canovee in a replay.

And, in 2011, the club gained Senior status by winning the Premier Intermediate County Championship for the first time.

In 2019, Newmarket won their first Duhallow Junior A Hurling Championship in 40 years beating Kilbrin on a scoreline of 1–22 to 2–11.
