Institution Saint-Louis de Gonzague is a primary and secondary Roman Catholic school in Port-au-Prince, Haiti.

The director at that time, Brother Ephrem Le-Mat, built a new campus on previously acquired land in the suburb of Delmas.

The eleventh, twelfth and thirteenth (Seconde, Rhéto, Philo) generally have three classes (yellow is dropped).

S. Roger Legagneur and Mona B. Anthony have held managerial roles in the secondary school until 2009.

The Secondary school building had minor damages comparatively but was not suitable for hosting students.

Primary school classes returned inside concrete buildings located in the Delmas campus in April 2014.
