Montreal (officially Montréal, ) is the most populous city in the Canadian province of Quebec and the second-most populous city in Canada. Originally founded in 1642 as 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 centred on the Island of Montreal, which got its name from the same origin as the city, and a few much smaller peripheral islands, the largest of which is Île Bizard.

Historically the commercial capital of Canada, Montreal was surpassed in population and in economic strength by Toronto in the 1970s. It remains an important centre of commerce, aerospace, transport, finance, pharmaceuticals, technology, design, education, art, culture, tourism, food, fashion, gaming, film, and world affairs.
