The Tubu or Toubou (Old Tebu: "Rock People") are an ethnic group inhabiting not only northern Chad but also southern Libya, northeastern Niger, and northwestern Sudan.

The Teda of Toubou live in the north of Chad around the Tibesti mountains.

They are generally studied as two closely associated people, particularly in the French literature, the Teda people and the Dazagra people.

They speak the Tebu languages, in the Saharan branch of the Nilo-Saharan language family.

Numbering about 0.5 million, they are Muslims. Toubou live either as herders and nomads, or as farmers near oases. Their society is clan-based, with each clan having certain oases, pastures and wells.

The Toubou people are also referred to as the Tibu, Tibbu, Tebu, Tubu, Tebou, Todga, Todaga, Toda, Tuda and Tudaga people.

Many of Chad's leaders have been Toubou, including presidents Goukouni Oueddei and Hissène Habré.[
