Colca River (possibly from Quechua qullqa deposit)[1] which downstream is called Majes and Camaná is a Peruvian river in the Arequipa Region that flows deep in the rugged Andes of southern Peru.

It originates south-east of the village Janq'u Lakaya (Ancolaccaya) in the Callalli District of the Caylloma Province.

[2] Near the town of Camaná the river empties into the Pacific Ocean.
