The 2021 All-Ireland Senior Football Championship was the 134th edition of the Gaelic Athletic Association's premier inter-county Gaelic football tournament since its establishment in 1887.
Thirty one of the thirty two Irish counties took part – Kilkenny did not compete. London and New York were withdrawn as a result of the public health restrictions imposed due to the COVID-19 pandemic.
Most division three and four teams who did not reach their provincial final were scheduled to compete in the 2021 Tailteann Cup. In previous years, they would have competed in the All-Ireland qualifiers.[1] The introduction of the Tailteann Cup competition was postponed until 2022 (having been originally postponed from 2020).
There was no "Super 8" group stage (officially the all-Ireland quarter-final group stage). The four provincial winners advanced to the All-Ireland semi-finals which were played as single knockout games.[2]
Dublin were the six-time defending champions, and were seeking to claim an unprecedented seventh consecutive title. Having won the Leinster championship, they were defeated by Mayo in the All-Ireland semi-finals.[3][4]
The All-Ireland final was played on 11 September 2021 at Croke Park in Dublin, between Tyrone and Mayo, in what was their first ever meeting in a final. Tyrone won their 4th title after a 2–14 to 0–15 win against Mayo.[5] Mayo lost their 11th consecutive final since 1989, losing 6 finals in 9 years, with this latest defeat on an identical scoreline to 2020, when Mayo lost to Dublin.[6]
