Dorobo (or Ndorobo, Wadorobo, Wandorobo, Torobo) is a derogatory umbrella term for several unrelated hunter-gatherer groups of Kenya and Tanzania that are subservient to the Maasai and have no cattle.
The term 'Dorobo' derives from the Maa expression il-tóróbò (singular ol-torróbònì) 'hunters; the ones without cattle'. Living from hunting wild animals implies being primitive, and being without cattle implies being very poor in the pastoralist Maa culture.
In the past it has been assumed that all Dorobo were of Southern Nilotic origin; accordingly, the term Dorobo was thought to denote several closely related ethnic groups.
Although many of them happen to be Nilotic, Dorobo as used by the Maa simply refers to neighbouring hunter-gatherers regardless of their origin — the Yaaku for example (present-day Mukogodo-Maasai) are an Eastern Cushitic people, the Aasax are of Southern Cushitic origin, while the Akie (Mosiro) are Eastern Nilotes. Some of the people described in early accounts of the 'El Dorobo' are imaginary, or fictional accounts of 20th century savages such as "races of bearded men" as described by Charles Hobley.
