École secondaire publique Louis-Riel (Louis Riel Public Secondary School) is a high school in the Blackburn Hamlet neighbourhood of Ottawa, Ontario, Canada, part of the Conseil des écoles publiques de l'Est de l'Ontario (Eastern Ontario Public School Board).

Phase 1 of the school's construction finished in 1980, accommodating 250 students from the Gloucester region in the east end of Ottawa.

Phase 2 was completed in 1982 featuring the school gymnasiums, cafeteria, and science and tech labs.

In 2005, a 12,422 square metres (133,710 sq ft) dome, North America's largest air supported fabric structure,[1] opened to the public.

Its construction was a joint project by the Ottawa Lions Track & Field Club and the CEPEO, and made it possible for Louis-Riel to offer a new Sports program to the region's students, in addition to providing extra track and field training facilities to the Ottawa Lions.
