The Tonawanda Kardex (also known as the Tonawanda Lumbermen and during its first season, the All-Tonawanda Lumberjacks) was an American football team active between 1916 and 1921. It played its games in Tonawanda, New York, a suburb of Buffalo with close ties to North Tonawanda, New York where American Kardex was founded. The team is most notable for its one game as a member of the American Professional Football Association (now the National Football League) in the 1921 season. They are easily the shortest-lived team in the league's history, and the shortest-lived known team in North American major league sports history.
