Lesotho (/ləˈsuːtuː/, Sotho pronunciation: [lɪˈsʊːtʰʊ]), officially the Kingdom of Lesotho (Sotho: 'Muso oa Lesotho), is an enclaved country within the border of South Africa. It is by far the largest of the world's three independent states completely surrounded by the territory of another country; with Vatican City and San Marino being the other two. Additionally, it is the only such state outside the Italian peninsula, and the only one that is not a microstate. Lesotho is just over 30,000 km2 (11,583 sq mi) and has a population of around 2 million. Its capital and largest city is Maseru. The official language is Sesotho.

Lesotho was previously the British Crown Colony of Basutoland, but it declared independence from the United Kingdom on 4 October 1966. It is now a fully sovereign state and is a member of the United Nations, the Commonwealth of Nations, the African Union, and the Southern African Development Community (SADC). The name Lesotho roughly translates to "land of Sesotho speakers"
