Denis Héroux, OC (French: [dəni eʁu]; 15 July 1940 – 10 December 2015) was a Canadian film director and producer.
Héroux wanted to become a teacher when he collaborated with Denys Arcand and Stéphane Venne on the 1962 film about life as a student, Alone or with Others (Seul ou avec d’autres).
By the late 1960s Héroux had become one of the most successful independent filmmakers with hits like 1968's Valérie and Here and Now (L'Initiation) in 1970.
In 1975, riding the success of several other popular features he directed, such as the swashbuckler Quelques arpents de neige (1973), he became involved in co-production projects and big-budget Quebec features as partner with his wife Justine Héroux in Cinévidéo.
He went on to helm international co-productions with films such as Jacques Brel Is Alive and Well and Living in Paris (1975), Atlantic City (1980), and Quest for Fire (1981).
