The Caribbean Alliance was a political entity on Earth located in the Caribbean Sea, and composed of former island nations and territories in that region, similar to the short-lived West Indies Federation of the late '50's and early '60's but encompassing all of the Caribbean rather than part of it.
Doctor Aristide, Chief Medical Officer of the USS Enterprise-C in 2344, was a native of the Caribbean Alliance. (TOS novel: Vulcan's Heart)
- Though not stated explicitly, information about Aristide and his background suggest that Haiti was a member nation of this alliance.
