Saint Vincent and the Grenadines (/ˌɡrɛnəˈdiːnz/), also frequently known simply as Saint Vincent, is an island country in the Caribbean. It’s located in the southeast Windward Islands of the Lesser Antilles, which lies in the West Indies at the southern end of the eastern border of the Caribbean Sea where the latter meets the Atlantic Ocean.

Its 369 km2 (142 sq mi) territory consists of the main island of Saint Vincent and the northern two-thirds of the Grenadines, a chain of 32 smaller islands. Some of the Grenadines are inhabited — Bequia, Mustique, Union Island, Canouan, Petit Saint Vincent, Palm Island, Mayreau, Young Island — while others are not: Tobago Cays, Baliceaux, Battowia, Quatre, Petite Mustique, Savan and Petit Nevis. Most of Saint Vincent and the Grenadines lies within the Hurricane Alley.

To the north of Saint Vincent lies Saint Lucia, to the east is Barbados, and Grenada lies to the south. Saint Vincent and the Grenadines is a densely populated country for its size (over 300 inhabitants/km2) with approximately 110,211 inhabitants.

Kingstown is the capital and main port. Saint Vincent has a British colonial history, and is now part of the Organisation of Eastern Caribbean States, CARICOM, the Commonwealth of Nations, the Bolivarian Alliance for the Americas and the Community of Latin American and Caribbean States (CELAC).
