Tín ngưỡng thờ Mẫu, or the Mother Goddess worship, is a traditional belief system in Vietnam that venerates female deities, particularly the Mẫu or Mother Goddesses. This practice is rooted in the agrarian culture of Vietnam, where the Mother Goddesses are seen as protectors of fertility, agriculture, and family. Rituals often include offerings, prayers, and ceremonies to seek blessings for prosperity and well-being. The worship of the Mother Goddesses is closely linked to the Tín ngưỡng thờ Tổ or ancestor worship, reflecting the importance of both maternal and ancestral figures in Vietnamese culture. This belief system has been recognized as an Intangible Cultural Heritage by UNESCO, highlighting its significance in promoting community identity and cultural continuity.
