All-Ireland Senior Football Championship

The All-Ireland Senior Football Championship (SFC) (Irish: Craobh Shinsir Peile na hÉireann) is the premier inter-county competition in Gaelic football. County teams compete against each other and the winner is declared All-Ireland Champions.

Organised by the Gaelic Athletic Association (GAA), the championship has been contested every year except one since 1887.

The final is played by the 35th Sunday of the year at Croke Park in Dublin, with the winning team receiving the Sam Maguire Cup. For the majority of its existence, the All-Ireland Championship has been played on a straight knockout basis whereby once a team loses they are eliminated from the championship. In more recent years, the qualification procedures for the championship have changed several times. Currently, qualification is limited to teams competing in six feeder competitions: the finalists of the four provincial championships (Connacht, Leinster, Munster and Ulster), the Tailteann Cup holders and the best non-qualified National Football League teams entering the 16-team group stage.

Thirty-three teams currently participate in the All-Ireland Championship, with Kerry, Dublin, Galway and Cavan being the most successful teams in their respective provinces.

The title has been won by 19 counties, 18 of which have won the title more than once. The all-time record-holders are Kerry, who have won the championship on 39 occasions. The current title holders (2026) are Mayo who defeated Kerry 1–20 to 1–17 at Croke Park on 26th July 2026.
