Saint Vincent and the Grenadines (i/sent vnsnt æn ð rndinz/) is an island-country in the Lesser Antilles chain, namely in the southern portion of the Windward Islands, which lie at the southern end of the eastern border of the Caribbean Sea where the latter meets the Atlantic Ocean. Its 389-square-kilometre (150 sq mi) territory consists of the main island of Saint Vincent and the northern two-thirds of the Grenadines, which are a chain of smaller islands stretching south from Saint Vincent Island to Grenada.

To the north of Saint Vincent lies Saint Lucia, to the east Barbados. Saint Vincent and the Grenadines is densely populated (over 300 inhabitants/km2) with its 120,000 people. Its capital is Kingstown, also its main port. The country has a French and British colonial history and is now part of the Organisation of Eastern Caribbean States, CARICOM, the Commonwealth of Nations and the Bolivarian Alliance for the Americas.

The island now known as Saint Vincent was originally named Hairouna ("The Land of the Blessed") by the native Caribs. The Caribs aggressively prevented European settlement on Saint Vincent until 1719. Prior to this, formerly enslaved Africans, who had either been shipwrecked or who had escaped from Barbados, Saint Lucia and Grenada and sought refuge in mainland Saint Vincent, intermarried with the Caribs and became known as Garifuna or Black Caribs.

Saint Vincent and the Grenadines has its own soccer league, the NLA Premier League, and also a national (association) football team. A notable Vincentian footballer is Ezra Hendrickson, the former national team captain who played at several Major League Soccer clubs in the United States and is now an assistant coach with the Seattle Sounders FC.

Saint Vincent and the Grenadines also have their own national rugby union team which are ranked 74th in the world.

Music popular in Saint Vincent and the Grenadine includes big drum, calypso, soca, steelpan and reggae. String band music, quadrille and be music and traditional storytelling are also popular.

The national anthem of Saint Vincent and the Grenadines is "Saint Vincent Land so Beautiful", adopted upon independence in 1979.
