Đạo Mẫu (Vietnamese: [ɗâːwˀ mə̌wˀ], 道母) is the worship of mother goddesses which was established in Vietnam in the 16th century. While scholars like Ngô Đức Thịnh propose that it represents a systematic worship of mother goddesses, Đạo Mẫu draws together fairly disparate beliefs and practices. These include the worship of goddesses such as Thiên Y A Na, Bà Chúa Xứ "Lady of the Realm", Bà Chúa Kho "Lady of the Storehouse", and Princess Liễu Hạnh, legendary figures like Âu Cơ, the Trưng Sisters (Hai Bà Trưng), and Lady Triệu (Bà Triệu), as well as the branch Four Palaces.
