RIC records from 1890 show that Ballymore Irish Brigade had 34 members with officers listed as Revd J McCarthy, John Byrne, Laurence Morrissey and Pat Keenan. The club affiliated 1887–1926. James Doyle and Anthony Corrigan attended the 1889 convention. Kilmoney near Baltinglass was also recorded as affiliated to Kildare GAA in a Leinster Leader of 1890. Ballymore participated in the first Kildare junior championship in 1906. In 1916 it left the GAA altogether over a dispute with the County Board over the right to appeal a decision, resulting from a dispute over the Junior Football final with Kilcullen. After that, Ballymore was a soccer town. One of its most famous sons was Jack Byrne of Bohemians and Shamrock Rovers.
Gaelic Football
Ballymore reformed in 1928 and won the county minor championship in 1943. That team came from Junior B in 1949 to win the Junior Championship in 1951, Intermediate Championship in 1952 and the Senior Championship in 1953. Larry Stanley trained the team that won the senior championship in 1953, his nephew Jim Clarke scored the winning goal. Clarke, Kevin Burke and Myles Doyle went on to star on Kildare football teams. Ten of the team had been on the side that won the Junior B championship five years earlier. No other club has won the junior, intermediate and senior championships in successive seasons in Kildare. They reached the 1956 county final and lost 1–6 to 0–4 against a Military College team that did not have a single Kildareman, and suffered the abuse of the press and the County Board after a rough match in which one Ballymore player was sent off, two players were expelled from the Association, and another was suspended for two months. Other achievements include a spectacular 6–3 to 0–3 victory over Kilcock in the Intermediate League final of 1951 which place in February 1953, when both were senior teams. There was an echo of the past when Ballymore won junior and intermediate championships in successive years 1985–1986. In 1985 Ballymore overcame the challenge of a strong Ballyteague side, while in 1986 they defeated hot favourites Suncroft in the final. They also defeated Castledermot in 1994 to regain the Intermediate Championship crown and Senior status. Ballymore have since been regraded and contest the Intermediate Championship. On 16 October 2010 Ballymore once more won the Intermediate Championship defeating Confey in a closely contested final. On 16 January 2011 Ballymore won the 2010 Leinster Intermediate Football Championship defeating Nobber by 0–12 to 0–10 in the delayed final played on their home pitch
Handball
Ballymore Eustace court was constructed during the First World War. A roof and gallery was added in the 1920s, in 1953 the walls were raised and lighting was installed in 1962. The club was affiliated to the Irish Amateur Handball Union until it ceased in 1935. Tommy Leahy was the leading IAHU player of the 1920s while Jack Byrne, Jack Byrne, Mick Dowling and Jim Dolan also won titles. When Ballymore affiliated to the GAA handball body in 1940, Mick Dowling came out of retirement to win junior and senior hardball titles within three years. Although softballs had been introduced in 1915 the leather hardball game was the prestige event of handball until the 1950s, winning five hardball titles. In 1979 Tom O'Rourke brought the first softball title to Ballymore when he beat Packie Ryan of Dublin. All of Kildare's top handballers of that era, Tom O'Rourke, Cecil and Pius Winders, Matt Purcell, Greg Lawlor and Michael Dowling came from Ballymore.
Camogie
A Ballymore team applied to the Kildare GAA board for recognition in 1921. Camogie was revived in the 1950s when the registered colours were maroon and again in 1980, when the registered colours were green and white.
