The 2017 O'Byrne Cup was played by county and further education college teams of Leinster GAA in January 2017 and was won by Dublin.
16 teams compete: 11 county teams (all those of Leinster except Kilkenny) and 5 third-level teams (DIT, UCD, IT Carlow, DCUâÂÂDóchas ÃÂireann and Maynooth University).
The teams are drawn into 4 groups of 4 teams each. Each team plays the other teams in their group once, earning 2 points for a win and 1 for a draw. The four group winners compete in the semi-finals.
