The Talgar (Kazakh: Талғар) is a river in Almaty Region, Kazakhstan.

[4] The Talgar river originates at the confluence of rivers Left Talgar and Right Talgar, which have their sources in a glacier area of the Trans-Ili Alatau range, part of the Tian Shan.

It flows northwards through a valley with steep slopes.

Since 1970 the river has had its mouth on the southern lakeshore of the Kapchagay Reservoir.

A string of small dams has been built in its last stretch, along with a network of irrigation channels.
