Guinea (pronounced /ˈɡɪni/, which is officially the Republic of Guinea French: République de Guinée), is a country in West Africa. Formerly known as French Guinea (Guinée française), it is today sometimes called Guinea-Conakry to distinguish it from its neighbor Guinea-Bissau. Conakry is the capital, the seat of the national government, and the largest city.
Guinea has almost 246,000 square kilometres (94,981 sq mi). It forms a crescent by curving from its western border on the Atlantic Ocean toward the east and the south. Guinea shares its northern border with Guinea-Bissau, Senegal, and Mali. Guinea shares its southern border with Sierra Leone, Liberia, and Côte d'Ivoire. The Niger River arises in Guinea and runs eastward.
Guinea is home to twenty-four ethnic groups. The most prominent groups are the Fula, Mandinka, and Susu.
