The Orange Tornadoes and Newark Tornadoes were two manifestations of a long-lived professional American football franchise that existed in some form from 1887 to 1941 and from 1958 to 1970, having played in the American Amateur Football Union from 1888 to 1895, the National Football League from 1929 to 1930, the American Association from 1936 to 1941, the Atlantic Coast Football League from 1963 to 1964 and 1970, and the Continental Football League from 1965 to 1969. The team was based for most of its history in Orange, New Jersey, with many of its later years in Newark. Its last five seasons of existence were as the Orlando Panthers, when the team was based in Orlando, Florida. The NFL franchise was sold back to the league in October 1930. The team had four head coaches in its two years in the NFL – Jack Depler in Orange, and Jack Fish, Al McGall and Andy Salata in Newark.

The Atlantic Coast Football League (ACFL) was a professional American football minor league that operated from 1962 to 1973. Until 1969, many of its franchises had working agreements with NFL and AFL teams to serve as farm clubs. The league paid a base salary of $100 per game and had 36 players on each active roster.
