The Cayman Islands, the most populous British Overseas Territory in the western Caribbean Sea, are self-governing. The three islands of Grand Cayman, Cayman Brac, and Little Cayman make up the 264-square-kilometer (102-square-mile) territory. These islands are between Jamaica and the Yucatán Peninsula in Mexico, south of Cuba and northeast of Honduras. Grand Cayman's capital, George Town, is the most populous of the three islands.

The Greater Antilles and the Western Caribbean Zone are both considered to include the Cayman Islands. Due in large part to the fact that the state does not impose taxes on any income earned or stored, the territory is a major international center for offshore financial transactions for wealthy individuals and international businesses.

The Cayman Islands have the highest standard of living in the Caribbean, with the highest GDP per capita. The Cayman Islands are home to immigrants from over 130 countries and territories.
