The Kisilyakh Range (Russian: Кисиляхский хребет; Yakut: Киһилээх) is a mountain range in the Sakha Republic, Far Eastern Federal District, Russia.

Some of the finest kigilyakhs in Yakutia are located in this range,[3] the tallest among them reaching a height of 30 meters (98 ft).

[2] The range consists of two ridges divided into an eastern and western part by a cleft.

[6] The Khadaranya and the Ymiysky ranges, other northern subranges of the Chersky Mountains, rise further to the east, beyond the Nenneli, a tributary of the Oldzho river.

The Adycha River flows across the range in its western part and the Tuostakh, one of its main tributaries, to the south.
