The Newcastle Australian Football League was an Australian rules football competition in the city of Newcastle, New South Wales, Australia.
The first clubs (Wallsend and Plattsburg) began in 1883, however the competition proper began in 1888 with teams contesting for the Black Diamond Cup, now Australia's oldest sporting trophy and presently contested in the Black Diamond Australian Football League.
In 1894, popularity of Australian rules waned. In 1948, after World War II, a 4 team competition was reborn - the first properly constituted competition in the region. The competing clubs were Waratah, Mayfield, Newcastle City and Broadmeadow.
After the 1999 season, the NAFL merged with the Central Coast AFL to form the Black Diamond Australian Football League.
