Tonawanda High School is a public high school located in the City of Tonawanda, New York, United States. It is part of the Tonawanda City School District.
The school's football field was at one time the home of the Tonawanda Kardex, a professional football team, which achieved fame by playing in just one game as a member of the National Football League in 1921. The Kardex would sometimes draw up to 3,500 fans for a game.[3] However, NFL records list the nonexistent "Lumbermen Stadium" as the team's home field.
