The 2021–22 All-Ireland Senior Club Football Championship was the 51st staging of the All-Ireland Senior Club Football Championship, the Gaelic Athletic Association's premier inter-county club football tournament. It was the first club championship to be organised in two years as the 2020-21 championship was cancelled due to the COVID-19 pandemic. The championship began on 21 November 2021 and ended on 12 February 2022. On 12 February 2022, Kilcoo won the championship. They defeated Kilmacud Crokes after extra time by 2-08 to 0-13 in the All-Ireland final at Croke Park.
