The Gaelic Athletic Association has been part of life in Newmarket since the closing years of the 19th century. The records show that the club fielded teams in the Cork Senior Football Championship of 1897 and 1901. The club's story begins really in 1927, when the junior footballers reached the Cork Junior Football Championship final against Urhan. The game, in which the club lost out to Urhan, was played in Killarney in March 1928. That same year they played in the Cork Senior Football Championship, losing to eventual winners Collins Barracks. The Duhallow division was founded in 1932 with the club having several successes in the Duhallow Junior A Hurling Championship, winning it on 15 occasions and leading the roll of honour up to the 1980s. Newmarket returned to the Cork Junior Football Championship final in 1950, losing out to Canovee in a replay. The County Junior Football title came to the club twice, in 1970 and 1998. And, in 2011, the club gained Senior status by winning the Premier Intermediate County Championship for the first time. The minor football team collected the County Minor A Football League title in 2005 having earlier been the runners up in the Championship final.In 2010, the Newmarket Minor Hurling team won the 12 aside C Hurling County Championship, becoming the first team ever to bring a County hurling title to town. In 2011, Newmarket GAA's Premier Intermediate Footballers won the county final. Newmarket played Senior Football in 2012 and 2013. 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.
