The 1946 All-Ireland Junior Football Championship was the 25th staging of the championship since its establishment by the GAA in 1912.

The competition format saw the four provincial champions compete in two 'Home' semi-finals, the winners of which then contested the All-Ireland 'Home' final.

In the last stage of the competition, the victorious 'Home' finalists then met the champions of Britain to determine who would be crowned overall All-Ireland Junior Football Champions for 1946.

The title match at Croke Park concluded with Down defeating Warwickshire, the champions of Britain, on a scoreline of 2–10 to 1–09.
