Suriname, officially the Republic of Suriname, (often incorrectly written as Surinam, but rectified in most up-to-date dictionaries. Some even call it the old-spelling) is a country in northern South America. In native tongue it is called Sranang. It was formerly known as Nederlands Guyana, Netherlands Guiana or Dutch Guiana. It lies in between French Guiana to the east and Guyana to the west. The southern border is shared with Brazil and the northern border is the Atlantic coast. The southernmost borders with Guyana and French Guiana are disputed (upper Corantijn and Marowijne rivers; the map shows the Guyana and French Guiana versions of the border). The country is the smallest sovereign state in terms of area and population in South America.
