The three Persian religions (Chinese: 唐代三夷教, Táng-dài sān yí jiào, transl. "Three Foreign Religions of the Tang Dynasty"), as a medieval Chinese concept, referred to a group of Iranian religions that spread to Tang China. They were recognized and protected under Tang rule, helping them to prosper in China at a time when Sassanid Iran was falling to the early Muslim conquests. The three religious movements identified by the term were Zoroastrianism, the Persian Church, and Manichaeism.
