École Père-Marquette, Secondary school in Rosemont-La Petite-Patrie, Montreal, Canada.

École Père-Marquette is a public French-language secondary school on Rue Marquette in La Petite-Patrie, Montreal. Its sports complex has four gymnasiums, a pool, an arena, a wrestling room and outdoor baseball, basketball and soccer fields plus a skateboard park. In 2019 it counted 1,310 students and 91 teachers.

The school opened in September 1970, and its first year began with a student strike over the right to wear jeans and smoke inside, granted after about two weeks. In 1995 it became Quebec's first Brundtland green school. A fire on 21 December 2006 started in the vocational wing; students shared Georges-Vanier until the rebuilt school reopened in September 2008.

The institution provides media arts programs for first to third-year students and digital cinema courses for fourth and fifth-year students.

The school stands on rue Marquette in La Petite-Patrie, in the Rosemont-La Petite-Patrie borough, served by the Montreal metro and bus network. It operates as an active public secondary school for grades 1 to 5, so the building and its sports complex are not open to the public during class hours. Access to the gymnasiums, pool and arena is arranged through the school.

The school's sports teams are called the Phénix. Its sports complex includes four gymnasiums, a pool, an arena, a wrestling room and outdoor baseball, basketball and soccer fields plus a skateboard park. In 2019 it counted 1,310 students and 91 teachers.
