Olyokma Nature Reserve (Russian: Олёкминский) (also Olekminsky) is a Russian 'zapovednik' (strict nature reserve) located south of the middle reaches of the Lena River on the right bank of its second largest tributary - the Olyokma River at the junction of the Aldan Highlands and the Olyokma-Chara Plateau in Olyokminsky District of the Sakha Republic (Yakutia).

[1][2] The region is in the foothills of southwest Yakutia, on the Aldan Highlands / Olyokma-Chara Plateau, an area cut by river valleys.

Within the borders of the reserve are 85 streams and rivers stretching from 3 to 110 km, acting as tributaries of the Olyokma, Tuolby, and Amga.

The dominant vegetation is light coniferous taiga with Dahurian larch Larix gmelini forming the canopy in areas with low snow cover.

There are a few 'ecotourist' routes in the reserve that are made available to a limited number of school groups and ecotourists accompanied by reserve guides, and which require permits to be obtained in advance.
