Mari religion (Mari: Чимарий йӱла, romanized: Čimarii jüla), also called Mari paganism, is the ethnic religion of the Mari people, a Volga Finnic ethnic group based in the republic of Mari El, in Russia. The religion has undergone changes over time, particularly under the influence of neighbouring monotheisms. In the last few decades, while keeping its traditional features in the countryside, an organised neopagan revival has taken place.
