Park Avenue (officially avenue du Parc in French) is one of central Montreal's major north-south streets. It derives its name from Mount Royal park, by which it runs. Between Mount Royal Avenue and Pine Avenue, the street serves as the boundary between the mountain, to the west, and the smaller Jeanne Mance Park to the east. South of Sherbrooke Street, the street's name changes to Bleury Street, and south of Saint Antoine Street in Old Montreal, the name changes again to Saint Pierre Street.
