The Caribbean is a region of the Americas consisting of the Caribbean Sea, its islands (most of which enclose the sea), and the surrounding coasts. The region is located southeast of Northern America, east of Central America, and to the north and west of South America.

Situated largely on the Caribbean Plate, the area comprises more than 7,000 islands, islets, reefs, and cayes.

The West Indies consist of the Antilles, divided into the larger Greater Antilles which bound the sea on the north and the Lesser Antilles on the south and east (including the Leeward Antilles), and the Bahamas.

The name "Caribbean" is named after the Caribs, one of the dominant Amerindian groups in the region at the time of European contact during the late 15th century. The analogous "West Indies" originates from Christopher Columbus' idea that he had landed in the Indies (then meaning all of south and east Asia) when he had actually reached the Americas. The Spanish term Antillas was commonly assigned to the newly discovered lands; stemming from this, "Sea of the Antilles" is a common alternate name for the Caribbean Sea in various European languages.

In the English-speaking Caribbean, someone from the Caribbean is usually referred to as a "West Indian", although the rather cumbersome phrase "Caribbean person" is sometimes used. The use of the words "Caribbean" and "Caribbeans" to refer to a West Indian or West Indians is largely unknown in the English-speaking Caribbean.
