Ashchykol (Kazakh: Ащыкөл) is a salt lake group in the Kyzylorda and Turkistan regions, Kazakhstan.

[2][3] Ashchykol is located in an arid region dominated by the sor type salt flats of the lower Sarysu basin.

It has very indented shores, forming a cluster of small lakes after the flood season that follows the melting of the snows, right before it goes completely dry.

The Boktykaryn river has its mouth at the northern end, but its waters rarely reach Ashchykol.

In years of sufficient rain the Chu river flows from the east into lake Akzhaykyn, located to the ESE.
