Pierrefonds Community High School (often abbreviated as PCHS), is a non-denominational, English speaking educational facility located in the Pierrefonds-Roxboro borough of Montreal, Quebec, Canada with an enrollment capacity of approximately 1,200 students, in grades 7 through 11.

PCHS began as an academic and vocational high school for both English and French speaking Catholic students to accommodate West Island population expansion at the beginning of the 1970s.

Originally conceived under the proposed name of Villa Nova, PCHS opened as Polyvalente de Pierrefonds Comprehensive High School, to better reflect its multi-disciplined approach.

In 2019, it was announced by Quebec Education Minister Jean-François Roberge that Riverdale High School would be merging with PCHS in an attempt to deal with overcrowding issues of the Commission scolaire Marguerite-Bourgeoys.

Designed by a California architect, as recommended by the school's first principal Mr. John Oss,[4] it employed industrial visual cues like unfinished concrete walls, exposed ceiling pipes and ducts that were painted primary red, blue and yellow enamel, and small windows that did not open.

Stylistically it was considered radical for an educational institution at the time, particularly due to the fact that the classrooms had no doors, an experiment that resulted in students sometimes being distracted by people passing by in the halls.
