Before Tomorrow (French: Le jour avant le lendemain) is a 2008 Canadian drama film, directed by Marie-Hélène Cousineau and Madeline Ivalu. The film is an adaptation of the novel Før Morgendagen by Danish writer Jørn Riel. It was the third film released by Igloolik Isuma Productions, an Inuit film studio best known for the film Atanarjuat: The Fast Runner, and is the first feature film to be made by Arnait Video Productions, a women's Inuit film collective.

Set in a small Inuit community in the Nunavik region of northern Quebec in the 1840s, the film stars Madeline Ivalu as Ninioq, an Inuk elder isolated with her grandson Maniq (Paul-Dylan Ivalu) after most of their community perishes from smallpox transmitted by strange traders. "Their adaptation moves the setting from northeast Greenland to northwest Ungava (Nunavik) and from the 1960s to the 1840s, when explorers and whalers began to trade with local Inuit and transmitted contagious diseases." The film was shot near Puvirnituq in Nunavik, northern Quebec.
