École secondaire Marie-Anne is a francophone public secondary mixed school located in the Ahuntsic-Cartierville borough in Montreal.

Part of the Centre de services scolaire de Montréal (CSSDM), it was originally in the Commission des écoles catholiques de Montréal (CECM) before the 1998 reorganization of school boards from religious communities into linguistic communities in Quebec.

[1] The building is modern, has four stories with lots of windows, and is on a green land with trees.

It contains mainly regular classrooms, rooms for computer labs, science labs, a cafeteria, a student café, a library, a weight room, a playroom, and an auditorium.

A transition school of 27 classrooms will be constructed in 2023 on the property to host temporarily a total of 464 students.
