Days of Darkness (French: L'Âge des ténèbres), also known as The Age of Ignorance, is a 2007 black comedy-drama film written and directed by Denys Arcand and starring Marc Labrèche, Diane Kruger and Sylvie Léonard. Presented as the third part of Arcand's loose trilogy also consisting of The Decline of the American Empire (1986) and The Barbarian Invasions (2003), it was followed by a fourth film with similar themes, The Fall of the American Empire (2018). The film follows a depressed québecois bureaucrat who, feeling insignificant, retreats into a fantasy world.

The film was screened out of competition at the 2007 Cannes Film Festival. It was nominated for four Genie Awards, including Best Motion Picture, and was shortlisted for the Academy Award for Best Foreign Language Film.
