West Indies, archipelago, between North and South America, curving c.2,500 mi (4,020 km) from Florida to the coast of Venezuela and separating the Caribbean Sea and the Gulf of Mexico from the Atlantic Ocean. The archipelago, sometimes called the Antilles, is divided into three groups: the Bahamas ; the Greater Antilles ( Cuba , Jamaica , Haiti , the Dominican Republic , and Puerto Rico ); and the Lesser Antilles ( Leeward Islands , Windward Islands , Trinidad and Tobago , Barbados ) and the islands off the northern coast of Venezuela.

The British dependent territories are the Cayman Islands , the Turks and Caicos Islands , Anguilla , Montserrat , and the British Virgin Islands . The Dutch territories are Aruba , Curaçao , Bonaire , Saint Eustatius , Saba , and part of Saint Martin . The French territories are Guadeloupe and its dependencies, part of Saint Martin, and Martinique . Puerto Rico is a self-governing commonwealth associated with the United States, and the Virgin Islands of the United States is a U.S. territory. Margarita belongs to Venezuela.

Many of the islands are mountainous, and some have partly active volcanoes. Hurricanes occur frequently, but the warm climate (tempered by northeast trade winds) and the clear tropical seas have made the West Indies a very popular resort area. Some 34 million people live on the islands, and the majority of inhabitants are of black African descent.
