Montreal (German [mɔntʁeˈa:l]) or Montréal (French [mɔ̃ʁeˈal], English [ˌmʌntɹiːˈɒl]) is a city of one million inhabitants in Canada. It is located in the southwest of the province of Quebec on Île de Montréal, the largest island in the High Elaga Archipelago, which is flowed around by the Saint Lawrence River and estuaries of the Ottawa. The neighbouring province of Ontario lies just under 60 kilometres to the west, the border with the USA just over 50 kilometres to the south. The cityscape is dominated by Mont Royal, a 233-metre-high range of hills of volcanic origin in the centre of the island, from which the city derives its name.

When the French navigator Jacques Cartier was the first European to explore the area in 1535, Saint Lawrence Iroquois lived on the island. In 1642, Paul Chomedey de Maisonneuve and Jeanne Mance founded Fort Ville-Marie, a Catholic mission station. This subsequently developed into the settlement of Montreal, which came under British rule in 1760. Montreal received its city charter in 1832. The city grew rapidly and developed into the economic and cultural centre of the country, but lost this leading role to Toronto in the last quarter of the 20th century. Significant events of global impact were the World Expo 67 and the 1976 Summer Olympics.

Montreal's economy is highly diversified. Important pillars of the service sector are financial services, media, trade and design. Tourism is also of great importance, due to the sights and the diverse cultural offerings, which include not only museums but also numerous festivals in the areas of film, theater and music. More than 60 international organizations have their headquarters in Montreal. The industrial sector is dominated by aeronautics, pharmaceuticals and high-tech companies. With four universities and several other colleges, Montreal is a major educational hub. The city is also a hub in the rail and road network and also has the largest inland port on the American continent.

With a population of 1,704,694 inhabitants (as of 2016), Montreal is the second largest city in Canada after Toronto and the largest in the province of Québec. The administrative region, which includes all municipalities on the island, has a population of 1,942,044 (as of 2016). The metropolitan area Communauté métropolitaine de Montréal, which includes urban areas in the immediate vicinity, has a population of 4,098,927 (as of 2016). French is Montreal's official language and the primary language of 56.9% of the population, while 18.6% speak primarily English. The remainder is made up of various immigrant languages, giving Montreal a multicultural population.

Montreal is the second largest city in the world after Paris where French is spoken as a native language. Montreal is also one of the largest cities in the world where French is the official language. The city used to be second to Paris, but has given up that rank to Kinshasa and Abidjan in recent years.
