North Trail High School is a senior high school located in the northeast community of Coventry Hills in Calgary, Alberta, Canada. The school's name is derived from the Siksika First Nation with historical significance from trails used by First Nations ancestors. North Trail High School offers the Advanced Placement (AP) program, French and Spanish second languages, and a variety of extracurricular activities. The school is part of the Calgary Board of Education's public school system.

The school had been planned for almost a decade before beginning construction, with students living in this area of the city having to go to schools several kilometer south such as John G. Diefenbaker High School and Crescent Heights High School, which could have up to a 50 minute travel time.

The Calgary Board of Education announced in December 2020 that construction will begin in early. The school finished construction around July 2023 opened for students on August 31, 2023.

Originally given the placeholder name of North Calgary High School, the official name was announced by the Calgary Board of Education Trustees on April 7, 2023, after consultations with a local First Nations elder, citing Siksika history. The grand opening ceremony of the school was held on April 26, 2024.
