Kyzylkol (Kazakh: Қызылкөл; Russian: Кызылколь) is a lake in Sozak District, Turkestan Region, Kazakhstan.

[1] The lake lies 20 kilometers (12 mi) east of Sholakkorgan town and a little to the west of Kumkent.

It lies at the bottom of a round basin, surrounded by two terrace-like concentric strips of terrain with takir and salt marsh near the shores.

The waters of the lake are brackish, turning to saline in the summer, when the riverbed dries and doesn't reach Kyzylkol.

The lake is an important place for the breeding, migrating and wintering of a number of water bird species, including the ruddy shelduck, northern shoveler, garganey, Eurasian teal, gadwall, mallard, common shelduck, greylag goose, little ringed plover and pale sand martin, as well as waders.
