Which is the largest French-speaking city in the world?

Kinshasa, formerly Léopoldville (Dutch: 'Leopoldstad'), is the capital and the largest city of the Democratic Republic of the Congo (DRC), and largest French-speaking city in the world. In 2016, the population of Kinshasa exceeded 12 million and became greater than the population of Paris.

Once a site of fishing and trading villages situated along the Congo River, Kinshasa is now one of the world's fastest growing megacities. It is located on the south side of the Congo River opposite Brazzaville. The two cities are the world's second-closest pair of capital cities (after Vatican City and Rome).

The city of Kinshasa is also one of the DRC's 26 provinces. Because the administrative boundaries of the city-province cover a vast area, over 90 percent of the city-province's land is rural in nature, and the urban area occupies a small but expanding section on the western side.

French is an official language in 29 countries across multiple continents, most of which are members of the Organisation internationale de la Francophonie (OIF), the community of 84 countries which share the official use or teaching of French. French is also one of six official languages used in the United Nations.
