Finality of Dusk is a 2023 Canadian post-apocalyptic science fiction film directed by Madison Thomas, from a screenplay by Thomas and Katarina Ziervogel. Starring Marika Sila, Cherrel Holder, Chris Dodd, and Meegwun Fairbrother, the film follows Ishkode (Sila) and Niife (Holder), who team up to survive in a world where the air has become too toxic for humans to breathe, requiring people to wear specialized breathing helmets at all times, all the while being pursued by Odin (Dodd), a deaf man who is on a mission to steal their helmets.

The film was shot in rural Manitoba in 2021. It made use of special sound design features to boost the filmgoing experience for deaf and hard-of-hearing audiences.
