The All-Ireland Junior Football Championship is a GAA competition It has historically consisted of two entirely different formats before and after 2021, but has retained the same name.
Since 2022, the competition has involved four Junior Gaelic football inter-county teams, It featured one team from Ireland who do not compete in the All-Ireland Senior Football Championship, Kilkenny, New York, and the winners and runners up from the All-Britain Junior Football Championship, one team from which, London, does play in the All-Ireland Senior Football Championship via the Connacht Senior Football Championship alongside New York. A second American team organized by the United States GAA, representing all other parts of the country outside New York, has entered the competition since 2024.
The current holders are New York, defeating London by 0-20 to 2-13 in the 2025 final. With three wins, New York are the most successful team in the post 2021 format.
Until 2021 the competition was previously held for all Junior Gaelic football inter-county teams in Ireland. In this previous format, the definition of what constituted a junior player differed from county to county. In some, the junior team was the second team after the senior team. This meant that any players who had not played with the senior team could play with the junior team. In others, such as Cork and Kerry, players could only be chosen from clubs within the county that played in junior or intermediate grades. These counties could not choose players from senior clubs, even if they were not on the senior county team. When a team won this championship, it had to pick a new team for the following year. No player could thus be on a winning team for two successive years.
Kerry are the most successful county in the competition's history from this period, having lifted the title on twenty occasions.. The 2008 championship was won by Dublin for the first time since 1960. Sligo defeated Kerry in 2010 to win their first title since 1935. Ulster did not participate in the Junior Championship for a period, Cavan the 2014 champions represented Leinster in the absence of an Ulster competition.
For the bulk of this competition's history up to 2021, the winners of the provincial Junior Football Championships met to decide who was the "Home" winner. This team then met the champion county in Great Britain to determine the All-Ireland Junior Football champion.
The five provincial winners would contest the All-Ireland Junior Football Championship.

At GAA Congress in 2021, a motion was passed to change the entire structure of the All Ireland Junior Football Championship competition to that of a mostly 'overseas competition' along with just one Irish county, Kilkenny. The Junior Football Championship competition therefore now involves just four teams: New York, Kilkenny, and the winner and runner-up of the British Junior Championship, all meeting in the All Ireland Junior Championship semi-finals.
But in 2025 Quarter-finals were brought in.
