The 2019–20 All-Ireland Senior Club Football Championship was the 50th staging of the All-Ireland Senior Club Football Championship since its establishment by the Gaelic Athletic Association in 1970-71.

[1] On 19 January 2020, Corofin won the championship following a 1-12 to 0-07 defeat of Kilcoo in the All-Ireland final at Croke Park.

Normally it is the club team that exited the championship at the highest stage.

Traditionally, the All-Ireland Club Championship Finals were held on St. Patrick's Day.

The GAA decided to bring forward the Club Finals to 19 January 2020 with a view to completing the competition in the calendar year from 2021.

The Kilkenny senior champions play in the Leinster Intermediate Club Football Championship.

London continue to compete in the Connacht championship – in previous years they played one of the provincial champions in a single match in December referred to as a quarter-final.

Traditionally, the All-Ireland final was played in Croke Park on St. Patrick's Day, the 17th of March, but it has also been moved to 19 January 2020.
