The West Indies is a subregion of North America, surrounded by the North Atlantic Ocean and the Caribbean Sea that includes 13 independent island countries and 18 dependencies and other territories in three major archipelagos: the Greater Antilles, the Lesser Antilles, and the Lucayan Archipelago.

The British West Indies, sometimes abbreviated to the BWI, is a collective term for the British territories historically established in the Anglo-Caribbean: Anguilla, the Cayman Islands, Turks and Caicos Islands, Montserrat, the British Virgin Islands, Antigua and Barbuda, The Bahamas, Barbados, Dominica, Grenada, Jamaica, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines and Trinidad and Tobago. Some definitions also include Bermuda, the former British Guiana and the former British Honduras although those territories are not usually considered part of the geographical West Indies. Before the decolonisation period in the later 1950s and 1960s the term was used to include all British colonies in the region as part of the British Empire. Following the independence of most of the territories from the United Kingdom, the term Commonwealth Caribbean is now used.

The Danish West Indies or Danish Antilles or Danish Virgin Islands was a Danish colony in the Caribbean, consisting of the islands of Saint Thomas with 32 square miles (83 km2); Saint John with 19 square miles (49 km2); Saint Croix with 84 square miles (220 km2), and Water Island with 491.5 acres (1.989 km2). The islands have belonged to the United States since they were purchased in 1917.

The Greater Antilles is a grouping of the larger islands in the Caribbean Sea, including Cuba, Hispaniola, Puerto Rico, Jamaica, and the Cayman Islands. Six island states share the region of the Greater Antilles in total, with Haiti and the Dominican Republic sharing the island of Hispaniola. Geologically, the Virgin Islands are also part of the Greater Antilles, though politically they are considered part of the Lesser Antilles. At an area of 207,411 square kilometres (80,082 sq mi), not counting the Virgin Islands, the Greater Antilles constitute nearly 90% of the land mass of the entire West Indies, as well as over 90% of its population. The remainder of the land belongs to the archipelago of the Lesser Antilles, which is a chain of islands to the east, running north–south and encompassing the eastern edge of the Caribbean Sea where it meets the Atlantic Ocean, as well as to the south, running east–west off the northern coast of South America. The Lucayan Archipelago is not considered to be a part of the Antilles archipelagos but rather of the North Atlantic.

The Leeward Passage is a channel between Hans Lollik Island and northern St. Thomas Island in the United States Virgin Islands in the West Indies. It is one of the smallest channels in the US.

The Lesser Antilles is a group of islands in the Caribbean Sea. Most form a long, partly volcanic island arc between the Greater Antilles to the north-west and the continent of South America. The islands form the eastern boundary of the Caribbean Sea with the Atlantic Ocean. Together, the Lesser Antilles and the Greater Antilles compose the Antilles. When combined with the Lucayan Archipelago, all three are known as the West Indies.

The Spanish West Indies or the Spanish Antilles were Spanish colonies in the Caribbean. In terms of governance of the Spanish Empire, The Indies was the designation for all its overseas territories and was overseen by the Council of the Indies, founded in 1524 and based in Spain. When the crown established the Viceroyalty of New Spain in 1535, the islands of the Caribbean came under its jurisdiction.

Sugar plantations in the Caribbean were a major part of the economy of the islands in the 18th, 19th, and 20th centuries. Most Caribbean islands were covered with sugar cane fields and mills for refining the crop. The main source of labor, until the abolition of chattel slavery, was enslaved Africans. After the abolition of slavery, indentured laborers from India, China, Portugal and other places were brought to the Caribbean to work in the sugar industry. These plantations produced 80 to 90 percent of the sugar consumed in Western Europe, later supplanted by European-grown sugar beet.
