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. They played their games in City of 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 their one game as a member of the National Football League, the shortest lived team in the league's history.
