Lake Sibinacocha (possibly from Quechua siwina whistle, qucha lake, lagoon) is a lake in Peru. It is ranked as the 22nd highest lake in the world. It is located in the Cusco Region, Canchis Province, Pitumarca District. The lake is situated at a height of approximately 4,873 metres (15,988 ft), about 15.19 km long and 2.86 km at its widest point, and drains into the Amazon River. Sibinacocha lies in the Vilcanota Range, south of Chumpe and southwest of Condoriquiña.
The lake contains Inca artefacts, some of which have been recovered from the lake.
An earthen dam was erected at the lake in 1996. It is 357 m (1,171 ft) long and 12 m (39 ft) high. The reservoir has a volume of 50,000 m3 (41 acre⋅ft) and a capacity of 110,000,000 m3 (89,000 acre⋅ft). It is operated by EGEMSA.
