Ogiek (also Okiek and Akiek) is a Southern Nilotic language of the Kalenjin family spoken or once spoken by the Ogiek peoples, scattered groups of hunter-gatherers in Southern Kenya and Northern Tanzania. Most if not all Ogiek speakers have assimilated to cultures of surrounding peoples: the Akiek in northern Tanzania now speak Maasai and the Akiek of Kinare, Kenya now speak Gikuyu. Ndorobo is a term considered derogatory, occasionally used to refer to various groups of hunter-gatherers in this area, including the Ogiek.
