Đạo Mẫu (Vietnamese: [ɗâːwˀ mə̌wˀ], 道母) is the worship of mother goddesses in Vietnam. While scholars like Ngô Đức Thịnh propose that it represents a systematic mother goddess cult, Đạo Mẫu draws together fairly disparate beliefs and practices. These include the worship of goddesses such as Thiên Y A Na, The Lady of the Realm (Bà Chúa Xứ), The Lady of the Storehouse (Bà Chúa Kho) and Princess Liễu Hạnh, legendary figures like Âu Cơ, the Trưng Sisters (Hai Bà Trưng), and Lady Triệu (Bà Triệu), as well as the cult of the Four Palaces. Đạo Mẫu is commonly associated with spirit mediumship rituals—known in Vietnam as lên đồng—much as practiced in other parts of Asia, such as Southern China, Myanmar (Mon people) and some community in India... Although the Communist government had initially proscribed the practice of such rituals, deeming them to be superstitions, they relented in 1987, once again legalizing their practice.
The most prominent form of Đạo Mẫu is Four Realms (Tứ Phủ), which worships a hierarchical pantheon of Vietnamese local deities with a strong influence from historical figures, Taoism and Buddhism. Four Realms is the most common in the North. Other forms in different areas have also developed an interference with other local beliefs.
The name literally means "Four Mansions", which includes the four realms Heaven, Highlands, Water and Earth.
