Dorobo (or Ndorobo, Wadorobo, Torobo) is a derogatory cover term for several unrelated hunter-gatherer groups of Kenya and Tanzania.
The term 'Dorobo' derives from the Maa expression il-tóróbò (singular ol-torróbònì) 'hunters; the ones without cattle'.
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, and the Akie (Mosiro) are Eastern Nilotes.
Believed to be the descendants of ancient San people, the Dorobo may have lived in southern Kenya and northern Tanzania longer than any of the other tribes who now inhabit these savanna lands.
Various Dorobo tribes believe in one god called Torooret, which means "very high." Others also refer to the god as Asiista, which is believed to derive from the great Egyptian gods Isis or Osiris.
The Dorobo are often isolated and live in tightly knit communal groups.
