List of defunct National Football League franchises
The following is a list and brief history of American football franchises that at one time played in the National Football League (NFL). The NFL was known as the American Professional Football Association (APFA) in 1920 and 1921. Note that the list represents NFL franchises that no longer exist, not franchises/teams that relocated. However, during the 1920s it is hard to tell if some teams changed nicknames from year to year or if each nickname represented a new franchise. It was also not uncommon for two or more teams to have the same nickname during the same season. No NFL franchise has folded since 1952. The Buccaneers, Colts, Cowboys, Giants, Lions, Panthers, and Texans franchises listed on this page are not the current franchises of those names. A defunct team, in this case, refers to a team which has had the rights to have a team returned to the NFL (or league collective at the time). Massillon Tigers attended the meetings in 1920, but never fielded a team in 1920.

These are all teams that applied to join the NFL but were refused entry. Some existed only as proposals, but others had full organizations. Unless otherwise noted, each team folded after their unsuccessful bid to join the NFL.
- Massillon Tigers (1920). Vernon Maginnis had acquired the rights to the Tigers name and had planned on using it for his traveling team in the NFL that year. Because of Maginnis's poor track record, Ralph Hay, owner of the Tigers' bitter rivals the Canton Bulldogs, declared himself owner of the Tigers name, immediately announced his Tigers would not play in 1920, and (in his capacity as Temporary Secretary of the league) prohibited any team in the league from scheduling games against Maginnis's Tigers.
- Union Quakers of Philadelphia (1922) An independent team that was not allowed into the league because of Pennsylvania's blue laws which would have prohibited the team from hosting Sunday home games. The Quakers, after four seasons of dormancy, would be reactivated as an AFL team.
- Youngstown Patricians (1922) A member of the Ohio League; the Patricians had a 1922 schedule laid out. The Patricians had been unable to pull a team together since the 1917 season ended, and 1922 was no exception, with the team canceling its season before it began.
- Los Angeles Bulldogs (1936) Approved as a probational franchise with the intention of becoming a full-fledged member in 1937. However, the Cleveland Rams were admitted in their place, due to travel cost concerns. The Bulldogs would go on to play in other leagues until 1948, while the Rams, coincidentally, would move to Los Angeles themselves in 1946.
- Pennsylvania Keystoners (1940) Proposed merger of the Philadelphia Eagles and Pittsburgh Pirates that was rejected by league ownership. A temporary merger was instituted in 1943 due to player shortages as a result of World War II.
- Buffalo Bills (AAFC) (1950) Members of the All-America Football Conference. Four NFL owners blocked Buffalo's entry into the NFL. Current Bills franchise is unrelated other than in name.
- Orlando Suns (1974). The Suns ownership group, led by Rommie Loudd, was one of the bidders on Central Florida's proposed NFL franchise; the NFL chose the Tampa Bay Buccaneers instead. The Suns played as the Florida Blazers in the World Football League.
- Memphis Grizzlies (1975) Members of the World Football League. Unsuccessfully sued NFL to attempt to force admission (see: Mid-South Grizzlies v. NFL).
- New Jersey Generals (1986). Members of the United States Football League. Owner Donald Trump was among those seeking to force a merger of the USFL and the NFL, but were unable to do so.
- Baltimore Bombers (1993). Proposed expansion team.
- Memphis Hound Dogs (1993). Proposed expansion team. Later played as Memphis Mad Dogs in CFL USA in 1995.
- St. Louis Stallions (1993). Proposed as both an expansion team and as a potential relocation of the New England Patriots.
