The
Mantaro River (, ) is a long river running through the central region of
Peru. Its
Quechua name means "great river". The word "Mantaro" may be a word originally from the
Ashaninka language, who live downstream along the
Ene River. The Mantaro, along with the
Apurimac River, holds the distinction of being the source of the
Amazon River, depending on the criteria used for definition.
