Séminaire Sainte-Marie is a French-speaking and Catholic private school based in Shawinigan, Quebec.
The institution was founded in 1950 as an all-boy classical college. In the wake of the education reform implemented during the Quiet Revolution, the Séminaire became a secondary school (middle and high school levels) and opened its doors to female students.
Well until the late 1980s, it offered compulsory Latin studies. The school has been hosting an IB Diploma Programme since 1998.
The Séminaire's former students include:
