Is Costa Rica a Caribbean country? In a way, yes. It’s mostly a matter of semantics…what does it mean to be a “Caribbean Country” anyway?
Does Costa Rica border the Caribbean Sea? Yes.
Natives and residents often refer to Costa Rica in terms of regions — Guanacaste, Pacific Side, Central Valley, and the Caribbean side, Limón, that identifies with Caribbean culture, a lot of people living there with a strong ethnic Caribbean background, speaking Jamaican Creole – Patois.
But no, Costa Rica is not referred to as a Caribbean country, but there’s certainly a good argument for it. Most people just refer to it as a Central American country with a distinctive Caribbean side.
Costa Rica is not an island and it doesn’t participate politically as part of the Caribbean Community (CARICOM or CC), an organization of fifteen Caribbean nations and dependencies
Geopolitically and culturally, Costa Rica is Central American, an isthmian region in North America.
