Autoroute 15 (also called the Décarie Expressway (English) or Autoroute Décarie (French) between the Turcot and Décarie Interchanges in Montreal and the Laurentian Autoroute (English) or Autoroute des Laurentides (French) north of Autoroute 40) is a highway in western Quebec, Canada. It was, until the extension of Autoroute 25 was opened in 2011, the only constructed north-south autoroute to go out of Montreal on both sides. A-15 begins at the end of Interstate 87 at the United States border at Saint-Bernard-de-Lacolle to Sainte-Agathe-des-Monts with an eventual continuation beyond Mont-Tremblant. The total length of A-15 is currently 164 km (101.9 mi), including a short concurrency (4 km or 2.5 mi) with Autoroute 40 (Boulevard/Autoroute Métropolitan) that connects the two main sections. This is one of the few autoroutes in Quebec that does not have any spinoff highways.
