The Ushbas (Kazakh: Үшбас) is a river in southern Kazakhstan.

[1][4] The Ushbas river has its origin in the northern slopes of the Karatau Range.

It heads roughly northwestwards down a deep mountain valley with steep sides.

In its final stretch it bends and flows roughly northwards, parallel to the Burkittі (Бүркітті), a left tributary of the Shabakty river, to the east.

In the summer, when the riverbed dries, the river doesn't reach Kyzylkol.
