The NFL Night Series was an Australian rules football tournament which was contested annually from 1976 until 1979. The tournament, played concurrently with the premiership season, was contested at different times by football clubs from the Victorian, South Australian, Western Australian and Queensland football leagues, and was operated by the National Football League, which was the national administrative body for the sport.
In 1977, a rival competition was established in Victoria in the form of the Australian Football Championships Night Series (AFC). From the 1980 season onwards, following termination of the NFL Night Series, it was effectively superseded by the AFC.
