September Five at Saint-Henri (French: À St-Henri le cinq septembre) is a 1962 National Film Board of Canada (NFB) documentary film directed by Hubert Aquin about the first day of school for children and their families in the working class Montreal district of Saint-Henri. As Aquin was primarily a writer, he worked with a variety of cameramen. The NFB credits 11 on the film—Guy Borremans, Michel Brault, Georges Dufaux, Claude Fournier, Bernard Gosselin, Jean Roy, Claude Jutra, Bernard Devlin, Arthur Lipsett, Don Owen and Daniel Fournier. Caroline Zéau in her book L'Office national du film et le cinéma canadien (1939-2003): éloge de la frugalité states that as many as 28 filmmakers worked on the project, including the entire French production team, with Jacques Godbout reading narration.

The film was originally released in French as a 42-minute film. The English-language version is shorter, with a 27-minute running time.
