Spanish-speakers are the most numerous in the Caribbean by far, with over 25 million native speakers in the Greater Antilles . English is the first or second language in most of the smaller Caribbean islands and is also the unofficial language of tourism, the dominant industry in the Caribbean region.

While many people associate the Caribbean primarily with English due to tourism, Spanish is actually the most spoken language in the region by a significant margin. Over 25 million people (approximately 64% of the Caribbean population) speak Spanish as their first language, primarily due to the high population densities in Cuba, the Dominican Republic, and Puerto Rico. French (including Haitian Creole) is the second most common, spoken by about 25% of the population, largely centered in Haiti. English ranks third, spoken by approximately 15% of the population across the various "Commonwealth" islands like Jamaica, Barbados, and the Bahamas. Dutch is the fourth major language, spoken in the ABC islands (Aruba, Bonaire, Curaçao) and Sint Maarten. In 2026, while English remains the lingua franca for the travel industry, the linguistic heart of the Caribbean remains firmly Hispanic.
