The Kulu (Russian: Кулу) is a river in Khabarovsk Krai and Magadan Oblast, Russia.

[4] The source of the river is in the eastern part of the Suntar Khayata Range, in Khabarovsk Krai.

The river flows roughly northeastwards across mountainous terrain, then it bends southwards and describes a wide arch northwards.

It divides into branches across a floodplain and finally it meets the Ayan-Yuryakh forming the Kolyma.

Its main tributaries are the Kenyelichi and Hinike from the right; and the Khujakh, Neryuchi and Arga-Yuryakh from the left.
