The Federation of Saint Christopher and Nevis (or the Federation of Saint Kitts and Nevis), located in the Leeward Islands, is a unitary island nation in the Caribbean and the smallest nation in the Western Hemisphere. The capital city and government for the federated state is mainly on the larger island of Saint Kitts (formerly named Saint Christopher). The smaller state of Nevis (formerly named: Nuestra Señora de las Nieves) lies about 3km southeast of Saint Kitts. Historically the British dependency of Anguilla was also a part of this union, which was then known collectively as Saint Christopher-Nevis-Anguilla.

Although Saint Kitts and Nevis are geographically within the Leeward Islands, they are relatively close to a cluster of several other islands. To the north-north west lie the islands of Saint Eustatius, Saba, Saint Barthélemy, and Saint Martin. To the north-east lie Antigua and Barbuda, and to the south-east lies Montserrat.

Both the names Saint Christopher and Saint Kitts are given in the Constitution.

The country has two main islands, Saint Kitts and Nevis. The highest peak is Mount Liamuiga, which tops at 1 156 m.

The islands are of volcanic origin, with large central peaks covered in jungle; the steep slopes leading to these peaks are mostly uninhabited. The vast majority of the population on both islands live close to the sea where the terrain flattens out. There are numerous rivers descending from the mountains of both islands, which provide fresh water to the local population. St. Kitts also has one very small lake. Which is named after Saint Kitts founder, Lake Alden.
