The Bukhtarma (Kazakh: Бұқтырма, romanized: Būqtyrma, بۇقتىرما, pronounced [bʊqtəɾˈmɑ]; Russian: Бухтарма, romanized: Bukhtarma) is a river of Kazakhstan.

It flows through East Kazakhstan Region, and is a right tributary of the Irtysh.

[1] The source of the river is in the Southern Altai Mountains.

The average water flow rate is 214 cubic metres per second (7,600 cu ft/s).

The lower course of the Bukhtarma has thus become of bay of the reservoir produced by the dam.
