Saint Vincent and the Grenadines is an island country in the eastern Caribbean. It is located in the southeast Windward Islands of the Lesser Antilles, which lie in the West Indies, at the southern end of the eastern border of the Caribbean Sea, where the latter meets the Atlantic Ocean.

The Caribbean is a subregion of the Americas that includes the Caribbean Sea and its islands, some of which are surrounded by the Caribbean Sea and some of which border both the Caribbean Sea and the North Atlantic Ocean; the nearby coastal areas on the mainland are sometimes also included in the region. The region is south-east of the Gulf of Mexico and Northern America, east of Central America, and north of South America.
