Mama Qucha
Also known as: Mamacocha, Mama Cocha

Mythological Narrative
The Sea Mother, named by colonial writers alongside Pachamama as the mother of waters, especially important to coastal fishing peoples and connected in highland thought to the lakes and springs that fed the fields.
Scholarly Commentary & Evolution
## Attestation
José de Acosta (1590), following Polo de Ondegardo, lists the sea, called Mamacocha, among the principal objects of Andean worship, and the seventeenth-century extirpators report coastal fishing communities making offerings to the sea. The word *qucha* means lake as well as sea, and highland people also addressed lakes, springs, and lagoons as sources of the water that became rain and irrigation.
## Water in Andean thought
The Huarochirí Manuscript describes a cosmos in which water circulates: the celestial llama Yacana drinks from the sea at night so that the ocean does not flood the world, and the Milky Way is a river in the sky. Spondylus shell (*mullu*), traded up from the warm waters off Ecuador, was among the most valued offerings throughout the Andes, a material link between the sea and highland rites for water.
## Limits of the record
No narrative myth about Mama Qucha herself survives in the major sources; she is known from lists of worshipped powers and from offering practices. This entry keeps to that evidence.
