Bà Chúa Xứ (Chữ nôm: 主處聖母, Chúa Xứ Thánh Mẫu, lit. “Holy Mother of the Realm”) is a prosperity goddess of southern Vietnam's Thanism. She is a tutelary of business, health, and a protector of the Vietnamese border. She is considered prestigious and is worshipped in her temple in Vĩnh Tế village at the foot of Sam Mountain, An Giang province. A three-day festival is held in the village at the beginning of the rainy season, beginning on the twenty-third day of the fourth lunar month, in her honour. Bà Chúa Xứ reached her peak of popularity in the 1990s and still entertains pilgrims every year with her responsiveness to loyal followers.
