Leinster Senior Club Football Championship
The Leinster Senior Club Football Championship is an annual Gaelic football tournament played on a knockout basis between the senior club championship winners of the competing counties in Leinster. The current holders of the Leinster title are Kilmacud Crokes from Dublin. Offaly side Gracefield were the first winners of the Leinster senior club football championship in the 1970–71 season. The most successful clubs are St. Vincent's, and Kilmacud Crokes from Dublin, and Portlaoise from Laois, who have won the Leinster championship on seven occasions. Carlow club Éire Óg won 5 championships in 7 years in the 1990s. Dublin clubs have won the Leinster championship twenty five times, which is more than triple any other county. The winner of this competition represents Leinster in the semi-finals of the All-Ireland Senior Club Football Championship.
