Tonawanda Middle/High School is a public school located in the 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. However, NFL records list the nonexistent "Lumbermen Stadium" as the team's home field.
In October 2000, the School District announced plans to begin a series of construction projects in early 2001 which would cost $26.4 million (equivalent to $ million in ). Pursuant to this plan, Tonawanda's middle and high schools were to occupy separate wings of the same building, now known as Tonawanda Middle/High School.
