The Caribbean is a region that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Sea and the North Atlantic Ocean) and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, and north of South America.

Situated largely on the Caribbean Plate, the region comprises more than 700 islands, islets, reefs and cays. These islands generally form island arcs that delineate the eastern and northern edges of the Caribbean Sea.

Geopolitically, the Caribbean islands are usually regarded as a subregion of North America and are organized into 30 territories including sovereign states, overseas departments, and dependencies. From December 15, 1954, to October 10, 2010, there was a country known as the Netherlands Antilles composed of five states, all of which were Dutch dependencies. From January 3, 1958, to May 31, 1962, there was also a short-lived political union called the West Indies Federation composed of ten English-speaking Caribbean territories, all of which were then British dependencies. The West Indies cricket team continues to represent many of those nations.
