Mayotte (French: Mayotte, pronounced: [majɔt]; Shimaore (Swahili dialect): Maore, [maˈore]; Malagasy: Mahori), officially the Departmental Collectivity of Mayotte (French: Collectivité départementale de Mayotte), is an overseas collectivity of France consisting of a main island, Grande-Terre (or Mahoré), a smaller island, Petite-Terre (or Pamanzi), and several islets around these two.
The archipelago is located in the northern Mozambique Channel in the Indian Ocean, namely between northwestern Madagascar and northeastern Mozambique. Mayotte’s area is 374 sq km, and with its estimated 194,000 people is very densely populated (520 inh/sq km). Its biggest city and prefecture is Mamoudzou. The territory is geographically part of the Comoro Islands, but has been politically separate since the referendum in the 1970s.
The territory is also known as Mahoré, the native name of its main island, especially by advocates of its inclusion in the Union of Comoros.
