Zhaksykylysh (Kazakh: Жақсықылыш; Russian: Жаксыкылыш) is a salt lake in Aral District, Kyzylorda Region, Kazakhstan.

Nowadays the Kyzylorda-based Araltuz company carries out the salt-mining operations.

The Zhaksykylysh Range, a mountain chain of moderate elevation, limits the lake to the northwest.

[5][6] Zhaksykylysh was affected by the drying of the Aral Sea basin in recent decades.

[7][6] The basin of the Zhaksykylysh is a grazing ground for local cattle during the spring, before the withering of the grass in the summer.
