Saint Kitts and Nevis, officially known as the Federation of Saint Christopher and Nevis, is an island country in the West Indies. Located in the Leeward Islands chain of the Lesser Antilles, it is the smallest sovereign state in the Western Hemisphere, in both area and population. The country is a Commonwealth realm, with Elizabeth II as Queen and head of state. It is the only federation in the Caribbean.
The capital city is Basseterre, located on the larger island of Saint Kitts. Basseterre is also the main port for both passenger entry and cargo. The smaller island of Nevis lies approximately 3 km to the southeast of Saint Kitts, across a shallow channel called The Narrows.
The British dependency of Anguilla was historically also a part of this union, which was then known collectively as Saint Christopher-Nevis-Anguilla. However, Anguilla chose to secede from the union and remains a British overseas territory. To the north-northwest lie the islands of Sint Eustatius, Saba, Saint Barthélemy, Saint-Martin/Sint Maarten and Anguilla. To the east and northeast are Antigua and Barbuda, and to the southeast is the small uninhabited island of Redonda and the island of Montserrat.
