All-Ireland Under-20 Football Championship

The GAA Football Under-20 All-Ireland Championship (known for sponsorship reasons as the Dalata Hotel Group GAA Football Under-20 All-Ireland Championship) is an annual inter-county Gaelic football competition organised by the Gaelic Athletic Association (GAA). It is the highest inter-county hurling competition for male players between the ages of 17 and 20 in Ireland. The championship was contested as the All-Ireland Under-21 Championship between 1964 and 2017 before changing to an under-20 age category from 2018.

The final, usually held in August, serves as the culmination of a series of games played during the summer months, and the results determine which team receives the Clarke Cup. The All-Ireland Championship has always been played on a straight knockout basis whereby once a team loses they are eliminated from the championship.

Four teams currently participate in the All-Ireland Championship, with the most successful teams coming from the province of Munster. Teams representing this province have won a total of 22 All-Ireland titles.

The title has been won by 16 different teams, 10 of whom have won the title more than once. The all-time record-holders are Cork, who have won the championship on 12 occasions. Tyrone are the current holders. The current Dalata Hotel Group Difference Maker of the Year, as selected by the Gaelic Writers Association, is Eoin McElhom from Tyrone.
