Saint Lawrence Boulevard or boulevard Saint-Laurent (its official name, in French) is a major street in Montreal, Quebec, Canada. A commercial artery and cultural heritage site, the street runs north-south through the near-centre of city and is nicknamed The Main.

The Main

Beginning at De la Commune Street at the edge of the Saint Lawrence River, it transects the Island of Montreal, passing through the boroughs of Ville-Marie, Le Plateau-Mont-Royal, Rosemont—La Petite-Patrie, Villeray–Saint-Michel–Parc-Extension, and Ahuntsic-Cartierville to Rue Somerville at the edge of Rivière des Prairies – a total length of about 11.25 km.

Saint Laurent Boulevard became a boulevard in 1905 and is often referred to as The Main. It serves as the city's physical division of east and west. Street numbers begin at Saint Lawrence and continue outward, with street names being suffixed by Ouest (West) or Est (East), depending on their orientation.
