The Olenti (Kazakh: Өлеңті; Russian: Оленти) is a river in the Akmola, Karaganda and Pavlodar regions, Kazakhstan.

[1] There are petroglyphs on the right bank of the lower course of the river, 10 km (6.2 mi) south-west of Tai village, part of the Ekibastuz City Administration.

It heads roughly northeastwards, skirting the feet of the eastern slopes of the range and bending northwards after a stretch.

[3][4][5] The Olenti flows within a narrow gorge, its width not surpassing 120 m (390 ft), as it heads roughly northwards beneath the mountainous area.

[1] The main fish species in the Olenti include pike, crucian carp, perch, roach and tench.
