Datooga (also Datog, Datoga, Taturu, Mang'ati, Tatoga or Tatog) is a Nilotic language or dialect cluster of the Southern Nilotic group. It is spoken by the Datooga people of the Great Rift Valley of Tanzania. The Sukuma name Taturu is also sometimes used in English; the Swahili name Mang'ati comes from Maasai, where it means "enemy". However, it is not considered offensive to the Datooga, as there is a degree of pride in being the historic enemy of the Maasai, and Mang'ati has become the standard name for the group in Swahili. In addition, numerous tribal and dialectal names may be found for the people or language as a whole.
