Ethnopluralism or ethno-pluralism is a European New Right theory of multiculturalism which contrasts with liberal multiculturalism. According to ethnomusicologist Benjamin Teitelbaum, the term ethnopluralism was coined by German sociologist Henning Eichberg in a 1973 essay and was later assimilated into the European New Right. 
"Cultural differentialism" is the view that cultures are clearly bound entities with a specific geographical location. From this perspective, global cultural diversity takes the form of cultural mosaic with a multiplicity of diverse cultures clearly delimited and with strict boundaries between them.
Ethnopluralists use the concept of cultural differentialism to assert a "right to difference" and argue for regional policies of ethnic separatism and racial separatism, but stress that each ethnic group and racial group should be considered equal on its own merit. This right-wing view of culture, ethnicity and race is increasingly popular in the ideological discourse of several right-wing and far-right groups in Europe since the 1970s, and has penetrated the discourse of a postmodern Left (i.e., Telos).
A leading proponent of ethnopluralism is the French New Right (Nouvelle Droite) philosopher Alain de Benoist, who claims that indigenous cultures in Europe are dying out and feels that pan-European nationalism based on ethnopluralism and "ethnoregionalism" would be the way to stop this.
Political scientist Alberto Spektorowski argues that cultural differentialism, which the European New Right opposes to racial superiority, leads precisely to European assertiveness and technological superiority. He further argues that an ethnoregional strategy contributes to a right-wing exclusionist vision of a culturally homogeneous, immigrant free and economically strong Europe.
