The 2017 All-Ireland Senior Hurling Championship was the 130th staging of the All-Ireland Senior Hurling Championship since its establishment by the Gaelic Athletic Association in 1887. The championship began on 23 April 2017 and ended on 3 September 2017. The draw for the championship was held on 13 October 2016 and was broadcast live on RTÉ2.

Tipperary, the 2016 champions, were defeated by Galway in the All-Ireland semi-final. Meath fielded a team in the championship for the first time since 2004.

On 3 September 2017 Galway won the championship following a 0–26 to 2–17 defeat of Waterford in the All-Ireland final. This was their fifth All-Ireland title and their first in 29 championship seasons.

The All-Ireland Senior Hurling Championship was a double-elimination tournament based on the Leinster and Munster provincial championships and the Christy Ring Cup. Fifteen teams took part.

The 2017 championship was the last to feature mostly knock-out Leinster and Munster championships. On 30 September 2017, the Special Congress held at Croke Park voted by 62% to restructure the Leinster and Munster championships as two provincial groups of five teams who competed on a round-robin basis.

The other Connacht teams could compete in the 2017 All-Ireland Senior Hurling Championship (tier 1) by gaining promotion through the tiers of hurling – the Christy Ring Cup (tier 2), the Nicky Rackard Cup (tier 3) and the Lory Meagher Cup (tier 4).
