Etnogenez (Grekçe ἔθνος (éthnos) 'insan grubu, ulus' and γένεσις (génesis) 'başlangıç, ortaya çıkış'; pl. ethnogeneses), bir etnik grubun oluşumu ve gelişmesidir.
The process of emerging ethnicity has been called 'ethogenesis,' the development and public presentation of a self-conscious ethnicity. [...] Roosens [1989: 47], in Creating Ethnicity, defined ethnogenesis as 'how people feel themselves to be a people and how they continue to maintain themselves as such,' even in the face of contradictory historical evidence.
