Down GAA

The county's most successful football club is Kilcoo. Kilcoo has won the Down Senior Football Championship on seventeen occasions, and also won the Ulster Senior Club Football Championship in 2019.

Down has won the All-Ireland Senior Football Championship on five occasions, most recently in 1994.

Down was not regarded as a football stronghold when Queen's University won the 1958 Sigerson Cup, and some of its leading players turned their thoughts to Down's county team dilemma. They took the 1959 Ulster title with six inter-changeable forwards who introduced off-the-ball running and oddities such as track-suits. In 1960 two goals in a three-minute period from James McCartan, Senior and Paddy Doherty helped beat Kerry, who were almost completely unbeaten at the time, and which brought to an end the Kerry football regime for a few years, and they beat Offaly by a point in 1961 in a tremendous match that featured five first half goals. In that three-year period their loyal supporters smashed every attendance record in the book. When Down played Offaly in 1961 they set a record attendance of 90,556 for a GAA game. Against Dublin in the 1964 National League final a record 70,125 showed up. The 71,573 who watched them play Kerry in 1961 still stands as a record for an All-Ireland semi-final. In 1968, Down beat Kerry with Sean O'Neill and John Murphy goals, again in a two-minute spell. Despite a famous prediction that Down would go on to win three-in-a-row, the county took twenty years to regain its status.

In 1991, they surprised favourites Meath, Barry Breen giving them the goal that sent them into a lead of eleven points with 20 minutes to go, too far even for Meath. In 1994, Mickey Linden sent James McCartan, Junior in for a goal directly under Hill 16 which silenced Dublin and helped them claim their fifth title.

Four Down hurling clubs, Ballycran, Ballygalget, Portaferry and Bredagh play in the Antrim League. The first two used the experience to win Ulster Senior Club Hurling Championships. Ballygalget, Portaferry and Ballycran play in Antrim Div 1 while Bredagh play in Div 3.

Clubs also contest the Down Senior Hurling Championship.

Down played in the Leinster Minor Hurling Championship for three years in the 1970s, even playing Antrim in an unusual Leinster semi-final at Croke Park in 1979. Although Down had not won the All-Ireland B championship in four final appearances, when the Ulster Senior Hurling Championship was revived, Down won titles in 1992, 1995 and 1997, losing the All-Ireland semi-finals by 14, 11 and 16 points. Down defeated Kilkenny in a Division 1 match in 1993 by a scoreline of 1–12 to 1–11. Down hurlers won the Christy Ring Cup for the first time in 2013, their greatest All-Ireland level success to date. This entitled them to enter the 2014 All-Ireland Senior Hurling Championship; however, Down opted to remain in the 2nd on this occasion.
