The Nilo-Saharan languages are a proposed linguistic family consisting of around 210 Native African languages spoken by somewhere around 70 million speakers, mainly in the upper parts of the Chari and Nile rivers, including historic Nubia, north of where the two tributaries of the Nile meet. The languages extend through 17 nations in the northern half of Africa: from Algeria to Benin in the west; from Libya to the Democratic Republic of the Congo in the centre; and from Egypt to Tanzania in the east.
As indicated by its hyphenated name, Nilo-Saharan is a family of the African interior, including the greater Nile Basin and the Central Sahara Desert. Most of its proposed constituent divisions are found in the modern countries of Sudan and South Sudan, through which the Nile River flows.
