France is divided into eighteen administrative regions, of which thirteen are located in metropolitan France, while the other five are overseas regions.

Metropolitan France, also known as European France, is the area of the French Republic which is geographically in Europe. This collective name for the European regions of France is used in everyday life in France but has no administrative meaning. 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 islands situated in the Atlantic Ocean, the English Channel and the Mediterranean Sea.

This article lists French regions and overseas collectivities by gross domestic product (GDP).
