The 1934 All-Ireland Junior Football Championship was the 17th 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 1934.
The title match concluded with Louth defeating London, the representatives of Britain, on a scoreline of 1–03 to 0–03. This was Louth's third triumph in the competition, following the county's earlier successes in 1925 and 1932.
