The Heirloom is a 2024 Canadian comedy film directed by Ben Petrie. Based in part on Petrie's own real-life relationship with actress Grace Glowicki, the film stars Petrie and Glowicki as Eric and Allie, a couple who decide to adopt a rescue dog during a COVID-19 lockdown. Despite the challenges of adapting to the new dog, Eric, a filmmaker who has been suffering from writer's block, then becomes inspired to start writing a new screenplay about a couple adopting a dog, with metafictional elements then starting to enter into the story as Eric begins "directing" the film in his head in real time.

The cast also includes Matt Johnson as a veterinarian, and Leah Doz as his veterinary technician.

The film, Petrie's full-length directorial debut, premiered on January 27, 2024, at the 53rd International Film Festival Rotterdam.
