Collège Saint-Joseph, Catholic secondary school in Chimay, Belgium

Collège Saint-Joseph is a Catholic secondary school in Chimay with buildings organized to accommodate students from ages 12 through 18. The institution provides both general academic education and vocational training across multiple subject areas and skill levels.

A Collège Saint-Bernardin existed in Chimay from 1673 until 1796; the town bought its buildings in 1802 and opened a communal college there in 1810. The Brothers of the Christian Schools ran a boys' school from 1837, and in 1877, at the request of the dean and Bishop Dumont of Tournai, the episcopal college was founded, its first stone laid on 27 March 1878. The east wing followed in 1954, coeducation began in 1970, and in 1982 the college joined the Institut Notre-Dame and Institut Saint-Joseph in the CES Saint-Joseph.

The school motto is Per ardua fortis, "courageous in difficulty". Each year the rhetoric students, the final-year class, organise the Chimay Spring Festival. The 1925 facade inscription "Collège Episcopal" and the MCMXXV date recall the bishop of Tournai's founding role.

The main brick building faces the street with its entrance under the stepped gable; the tall slate spire marks the left end of the facade. The school is an active secondary institution, so visits are best arranged with the administration outside lesson hours. The sports centre built in 1976 and the workshops rebuilt in 2005 are on the school grounds.

The school's motto is Per ardua fortis, "strong through difficulties". In 2009 it won the Belgian Energy and Environment Prize for its project hosted at erecole.be. Each year the final-year pupils (rhétoriciens) organise the Chimay Spring Festival.
