All-Ireland Junior Football Championship

The All-Ireland Junior Football Championship is an inter-county competition in Gaelic football in which county teams play one another and the winner is declared All-Ireland Junior Champions. It is organised by the Gaelic Athletic Association and has been contested since 1912 under two different formats that kept the same name. In Gaelic games the word junior marks the tiers below senior and intermediate competition and does not refer to age, so the sides were second-rank county teams whose definition of a junior player differed from county to county. Between 1912 and 2021 the championship was played between junior county teams in Ireland and, from 1928, with the champions of Britain in the final stages; since 2022 it has been contested by the All-Britain winners and runners-up alongside Kilkenny, New York and USGAA. Kerry hold the record for the pre-2021 period with twenty titles, and New York lead the post-2021 format with three.
