While the Caribbean region was heavily influenced by Dutch colonization, the languages spoken in the Caribbean islands today are predominantly English, Spanish, French, and Creole languages.
However, you may be thinking of Dutch Caribbean territories:
* Aruba
* Curaçao
* Sint Maarten
* Bonaire
* Sint Eustatius
* Saba
These territories are part of the Kingdom of the Netherlands and their official language is Dutch. However, they are not independent countries.
