The 2009 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. The winners of the 2009 O'Byrne Cup were Louth.[1] [2]
The eight winning teams from the first round of the O'Byrne Cup go on to qualify for the quarter-finals of the tournament. The losers of the first round go on to the O'Byrne Shield quarter finals.
The teams included in the quarter-finals of the O'Byrne Shield were Offaly, Carlow, Wexford, Laois, Kilkenny, UCD, Athlone IT and Westmeath. Laois were the eventual winners in the final against Carlow.
