The 2019 All-Ireland Senior Hurling Championship is the 132nd staging the Athletic Association’s premier inter-county hurling tournament, of this All-Ireland Senior Hurling Championship, as its establishment in 1887. The attraction for the 2019 fittings happened on 11 October 2018. The tournament started on 11 May 2019 and can be scheduled to end on 18 August 2019. Limerick are the defending champions. Carlow came back to the Leinster Championship for the first time since 2016, substituting Offaly who were relegated in 2018. Carlow lost all their four games in 2019 and so were automatically relegated to the 2020 Joe McDonagh Cup. They were advertised in 2018.
