Norwin High School is a public high school located in North Huntingdon, Pennsylvania, with a current enrollment of approximately 1,600 students in grades 9-12. It enrolls students from North Huntingdon, Irwin, and North Irwin and is part of the Norwin School District.

In 1914, the township of North Huntingdon and boroughs of Irwin and North Irwin signed a jointure to combine their three high schools. The original merged high school (now Queen of Angels Catholic School) was built in 1916 and named Norwin Union High School. The west wing of the building was destroyed by a fire in 1944 (which severed the jointure between North Huntingdon, Irwin, and North Irwin) and the remaining structure became North Huntingdon High School. In 1950, a new west wing was constructed and the jointure between North Huntingdon, Irwin, and North Irwin was reinstated in 1958. By 1964, the building was being outgrown by its student population; as a result, Norwin’s Board of Education approved the purchase of the nearby McMahon Farm where the present-day high school was built in 1965. It underwent massive renovations, which were completed in 2006.
