Route 131 is a Quebec highway running from Lavaltrie (junction of Route 138) to Saint-Michel-des-Saints in Lanaudière. This route, combined with Autoroute 31, provides the key route to Joliette, and then continues northward through Saint-Félix-de-Valois, Saint-Jean-de-Matha and Saint-Zénon for a distance of approximately 125km (78miles).
The route is name-dropped in the opening lyrics of the song "Le Shack à Hector" by Repentigny-based neo-trad band Les Cowboys Fringants.
