The Jengu (plural miengu) are water spirits in the traditional beliefs of the Sawabantu groups of Cameroon, including the Duala and Bakweri peoples. They are typically said to be beautiful, mermaid-like beings with long hair and lovely gap-teeth.
They bring good fortune to those who worship them, can cure disease, and act as intermediaries between worshippers and the world of spirits. They stand at the centre of the annual Ngondo ceremony, held in Douala since 1949.
