The Olenyok (Russian: Оленёк, sometimes spelled Оленек, Olenek; Yakut: Өлөөн, Ölöön) is a major river in northern Siberian Russia, west of the lower Lena and east of the Anabar. It is 2,292 kilometres (1,424 mi) long, of which around 1,000 kilometres (620 mi) is navigable. Average water discharge is 1,210 cubic metres per second (43,000 cu ft/s).

The Olenyok is known for its abundance in fish. It is frozen for over eight months every year and the climate in its area is harsh because of the direct influence of the Arctic.
