Lembus is one of the sub tribes of kalenjin people. Lembus group is sub-divided into Pokor, Keben, Bogor, Kakimor, Kamaruso, Somek, Murkaptuk, Agiekablembus, Chepkero, Kapkosom and Emom. They settled in Emom, Chepkero, ElKamaruso, Kakimor, Keben, Bogor, Lembus Mosop, Lembus Soin, Lembus Kongasis(east), Lembus Kiptuiya(west). Other areas are Keiyo and Laikipia. Etc[citation needed].
The Lembus people are perceived to be Tugen people, but this assertion has been rejected by the Lembus themselves, and their Lembus Council of Elders based on migration history, cultural practice and language[citation needed] Members of the Lembus community insist that Tugen is just a name coined in the 1960s to unite the small communities living in Baringo. In 2019 the lembus people moved to court demanding to be recognized as a distinct ethnic group and not as a sub-tribe of the Tugen[citation needed]
