蒙特利尔（法语：Montréal，[mɔ̃ʁeal]；英语：Montreal，/ˌmʌntriːˈɒl/  ），，是一座位于加拿大魁北克省西南部的城市，主要位于圣劳伦斯河和渥太华河汇合处的蒙特利尔岛及周边小岛上。根据2011年人口普查，蒙特利尔人口约为342万，是魁北克省内最大城市、加拿大第二大城市及北美第十五大城市。「蒙特利尔」一词来源于中古法语「Mont Royal」，意思为「皇家山」，至今蒙特利尔城中心的地标皇家山仍以此命名。法语是蒙特利尔的官方语言，也是城市里最常用的语言，使用人口占城市总人口的60.5%，使得蒙特利尔成为世界上仅次于巴黎的第二大法语城市。

Montreal (/ˌmʌntriːˈɒl/; pronounced: [mɔ̃ʁeal]; French: Montréal) is the largest city in the Canadian province of Quebec. It is the second largest city in Canada, 18th largest in North America and the 26th largest in the Americas. Originally called Ville-Marie, or "City of Mary," it is named after Mount Royal, the triple-peaked hill in the heart of the city. The city is on the Island of Montreal, which took its name from the same source as the city, and a few much smaller peripheral islands, the largest of which is Île Bizard. It has a distinct four-season continental climate with warm to hot summers and cold snowy winters.
