# 2023 All-Ireland Junior Football Championship

The 2023 All-Ireland Junior Football Championship was the 91st staging of the All-Ireland Junior Football Championship since its establishment by the Gaelic Athletic Association in 1912. The championship ran from 14 July to 16 July 2023.
Kilkenny were the defending champions.
New York won the 2023 title. It was their first ever championship in football and their first piece of silverware since winning the 1966–67 National Football League.

## Format

Since 2022, the All-Ireland Junior Championship has been confined to just four teams; New York, Kilkenny and the winner and runner-up of the British Junior Football Championship. Prior to the change, the championship previously featured a provincial structure for all junior Gaelic football inter-county teams in Ireland.
