The Orphan Muses (French: Les Muses orphelines) is a Canadian drama film, directed by Robert Favreau and released in 2000. An adaptation of the play by Michel Marc Bouchard, the film stars Marina Orsini, Céline Bonnier, Stéphane Demers and Fanny Mallette as a group of adult siblings dealing with the revelation of a longtime family secret.

The Tanguay siblings grew up as orphans, after their father died and their mother (Louise Portal) ran off with her new lover. Although older siblings Catherine (Orsini), Martine (Bonnier) and Luc (Demers) knew the truth, they conspired to protect their emotionally fragile youngest sister Isabelle (Mallette) by telling her that their mother was dead as well. The film's plot centres on the fallout within the family of the now adult but still emotionally immature Isabelle finally learning the truth that their mother is still alive and simply abandoned them.
