Overseas departments and regions of France in the context of "French Guiana"

France is divided into eighteen administrative regions (French: régions, singular région [ʁeʒjɔ̃]), of which thirteen are located in metropolitan France (in Europe), while the other five are overseas regions (not to be confused with the overseas collectivities, which have a semi-autonomous status).

All of the thirteen metropolitan administrative regions (including Corsica as of 2019) are further subdivided into two to thirteen administrative departments, with the prefect of each region's administrative centre's department also acting as the regional prefect. The overseas regions administratively consist of only one department each and hence also have the status of overseas departments.

As of January 2019, there were 473 communes in France (metropolitan territory and overseas departments and regions) with population over 20,000, 280 communes with population over 30,000, 129 communes with population over 50,000 and 42 communes with population over 100,000. All figures reflect the municipal population (French: population municipale), meaning people who have their usual residence in the commune, excluding population counted apart. The population of the matching urban unit is usually several times that of its central commune. Populations as of 2006 and 2013 are also shown. Communes in the overseas and sui generis collectivities are listed in a separate table below.

This is a list of countries with territory that straddles more than one continent, known as transcontinental states or intercontinental states.

Contiguous transcontinental countries are states that have one continuous or immediately-adjacent piece of territory that spans a continental boundary, most commonly the line that separates Asia and Europe. By contrast, non-contiguous transcontinental countries are those states that have portions of territory that are separated from one another either by a body of water or by other countries (such as in the case of France). Most non-contiguous transcontinental countries are countries with dependencies like United Kingdom with its overseas territories, but can be countries that have fully integrated former dependencies in their central states like France with its overseas regions.

Seychelles (/seɪˈʃɛl(z)/ , /ˈseɪʃɛl(z)/; French: [sɛʃɛl] or [seʃɛl]), officially the Republic of Seychelles (French: République des Seychelles; Seychellois Creole: Repiblik Sesel), is an island country and archipelagic state consisting of 115 islands in the Indian Ocean. Its capital and largest city, Victoria, is 1,500 kilometres (800 nautical miles) east of mainland Africa. Nearby island countries and territories include the Maldives, Comoros, Madagascar, Mauritius, and the French overseas departments of Mayotte and Réunion to the south; and the Chagos Archipelago to the east.Seychelles is the smallest country in Africa as well as the least populated sovereign African country, with an estimated population of 100,600 in 2022.

Seychelles was uninhabited prior to being encountered by Europeans in the 16th century. It faced competing French and British interests until it came under full British control in the early 19th century. Since proclaiming independence from the United Kingdom in 1976, it has developed from a largely agricultural society to a market-based diversified economy, characterised by service, public sector, and tourism activities. From 1976 to 2015, nominal GDP grew nearly 700%, and purchasing power parity nearly 1600%. Since the late 2010s, the government has taken steps to encourage foreign investment.

Mayotte (/maɪˈɒt/ my-OT; French: Mayotte, [majɔt] ; Shimaore: Maore, IPA: [maˈore]; Kibushi: Maori, IPA: [maˈori]), officially the Department of Mayotte (French: Département de Mayotte), is an overseas department and region and single territorial collectivity of France. It is one of the overseas departments of France as well as one of the 18 regions of France, with the same status as the departments of Metropolitan France. It is an outermost region of the European Union and, as an overseas department of France, part of the eurozone.

Mayotte is located in the northern part of the Mozambique Channel in the western Indian Ocean off the coast of Southeastern Africa, between the northwestern part of the island of Madagascar and northeastern Mozambique on the continent. Mayotte consists of a main island, Grande-Terre (or Maore), a smaller island, Petite-Terre (or Pamanzi), as well as several islets around these two. Mayotte's land area is 374 square kilometres (144 sq mi) and, with its 320,901 people according to January 2024 official estimates, is very densely populated at 858 inhabitants per km (2,228 per sq mi). The biggest city and prefecture is Mamoudzou on the larger Grande-Terre. The Dzaoudzi–Pamandzi International Airport is located on the neighbouring smaller island of Petite-Terre. The territory is also known as Maore, the native name of its main island.

Metropolitan France (French: France métropolitaine or la Métropole), also known as European France (French: le territoire européen de la France), is the area of France which is geographically in Europe and chiefly comprises the mainland, popularly known as "the Hexagon" (French: France hexagonale or l'Hexagone), and Corsica. This collective name for the European regions of France is used in everyday life in France but has no administrative meaning, with the exception that only Metropolitan France is part of the Schengen Area. Indeed, the overseas regions have exactly the same administrative status as the metropolitan regions. Metropolitan France comprises mainland France and Corsica, as well as nearby French islands in the Atlantic Ocean, the English Channel and the Mediterranean Sea waters. Its borders have undergone significant changes over the centuries, particularly in the east, but have remained substantially unaltered since 1962.

In contrast, overseas France (France d'outre-mer) is the collective name for all the French departments and territories outside Europe. Metropolitan and overseas France together form the French Republic. Metropolitan France accounts for 82.0% of the land territory, 3.3% of the exclusive economic zone (EEZ), and 95.9% of the population of the French Republic. Some small parts of France (e.g. Cerdanya) are a part of the Iberian Peninsula.

Overseas France (French: France d'outre-mer, also France ultramarine) consists of 13 French territories outside Europe, mostly the remnants of the French colonial empire that remained a part of the French state under various statuses after decolonisation.

"Overseas France" is a collective name; while used in everyday life in France, it is not an administrative designation in its own right. Instead, the five overseas regions have exactly the same administrative status as the thirteen metropolitan regions; the five overseas collectivities are semi-autonomous; and New Caledonia is an autonomous territory. Overseas France includes island territories in the Atlantic, Pacific and Indian oceans, French Guiana on the South American continent, and several peri-Antarctic islands as well as a claim in Antarctica. Excluding the district of Adélie Land, where French sovereignty is effective de jure by French law, but where the French exclusive claim on this part of Antarctica is frozen by the Antarctic Treaty (signed in 1959), overseas France covers a land area of 120,396 km (46,485 sq mi) and accounts for 18.0% of the French Republic's land territory. Its exclusive economic zone (EEZ) of 9,825,538 km (3,793,661 sq mi) accounts for 96.7% of the EEZ of the French Republic.

France has, due to its overseas departments and regions that are scattered in all the oceans of Earth, the largest exclusive economic zone in the world. The total EEZ of France is 10,911,921 km (4,213,116 sq mi).

It covers approximately 7% of the surface of all the EEZs of the world, while the French Republic is only 0.45% of the world's land surface.
