2019 Leinster Senior Hurling Championship

The 2019 Leinster Senior Hurling Championship is the 2019 installment of the annual Leinster Senior Hurling Championship organised by Leinster GAA.

Galway were the defending champions, but were eliminated in controversial circumstances in Round 5 and finished fourth in the province, despite having the same number of points as Dublin and Leinster finalists Kilkenny and Wexford. Wexford defeated Kilkenny in the final.

Teams
The Leinster championship was contested by four counties from the Irish province of Leinster, as well as one county from the Irish province of Connacht, where the sport is only capable of supporting one county team at this level.
