The 2008 O'Byrne Cup was a Gaelic football competition played by the teams of Leinster GAA. The competition differs from the Leinster Senior Football Championship as it also features further education colleges and the winning team does not progress to another tournament at All-Ireland level. Last years winners of the O'Byrne Cup were Dublin. The first game was between defending champions Dublin and Wicklow, Dublin won the game comfortably.
