Bowness High School is a public school in Calgary, Alberta, Canada, which teaches grades 10 through 12. It is operated by the Calgary Board of Education.

The school was founded in 1956 as a junior and senior high school to serve the town of Bowness . In 1964 the town was annexed by Calgary. No longer having a junior high component, the school now serves several Calgary communities in addition to Bowness.

Some of the programs of the school include Pre-Engineering, Career and Technology Studies (CTS) and High Performance Athlete Development (HPAD). Bowness has an award-winning band program.

In 2016 Bowness officially opened its newly constructed southern wing of the school. This newly expanded wing comprises six new classrooms, a fully functioning culinary arts kitchen/cafeteria, fitness centre and Cosmetology; along with various common learning areas and new main foyer.
