The 2020 All-Ireland Senior Hurling Championship was the 133rd staging of the All-Ireland Senior Hurling Championship, the Gaelic Athletic Association's premier inter-county hurling tournament, since its establishment in 1887. The 2020 fixtures were announced in October 2019. Games were initially scheduled to begin on 9 May 2020. Due to the impact of the COVID-19 pandemic on Gaelic games, the competition was delayed before beginning on 24 October 2020 and ending on 13 December 2020.

Laois returned to the Leinster Championship for the first time since 2017, replacing Carlow who were relegated in 2019. Tipperary entered the championship as the defending champions and were attempting to retain the title for the first time since 1965. They were knocked out at the All-Ireland quarter final stage following a defeat by Galway.

On 13 December 2020, Limerick won the championship after a 0-30 to 0-19 win over Waterford in the All-Ireland final at Croke Park. It was their ninth championship title overall and their first title since 2018.

Waterford's Stephen Bennett was the championship's top scorer with 1-54.

Format

Initially, the 2020 All-Ireland hurling championship format was to feature five-team groups in both Leinster and Munster and the two Joe McDonagh Cup finalists in the format introduced in 2018 for an initial three-year period. At the GAA Congress on 29 February 2019 it was decided to expand the Leinster Hurling Championship from five to six teams, beginning in 2021. This meant there would be no relegation from the Leinster Hurling Championship in 2020 and that the winners of the Joe McDonagh Cup would be promoted.

Due to the COVID-19 pandemic in Ireland, some changes were announced on 26 June 2020. The format reverted to knockout provincial championships, along with qualifiers, similar to the 2017 format. The two Joe McDonagh Cup finalists did not compete in the senior championship.
