The Institut Florimont is a private school in Geneva, Switzerland. It was founded in 1905 by the Congrégation des Missionnaires de Saint François de Sales, soon after a law in France prohibited religious congregations of any persuasion. The Institut Florimont started out as a private catholic French-speaking boarding school for boys.

However, the school has been directed by a lay person since 1995, and has accepted girls at the secondary II level since 1978. In 1995, the entire school became co-ed, boarding was no longer offered, and the pre-school classes were opened.
