The Hedareb or T'bdawe are a Cushitic ethnic group native to northwestern Eritrea. They are a subgroup of the Beja. They are more diverse than the other Eritrean ethnicities; one subgroup speaks the traditional Beja language, which belongs to the Cushitic branch of the Afro-Asiatic family, while another is more closely related to Sudanese Hadendoa. They are among the least-researched groups in Eritrea.
