The Nelgesin Range (Russian: Нельгесинский хребет)[1][2] is a mountain range in the Sakha Republic (Yakutia), Far Eastern Federal District, Russia.

[4] The Nelgesin Range rises in the area of the Yana-Oymyakon Highlands, part of the Chersky Mountains, to the west of the Adycha and north of the Derbeke.

[4] It stretches in a roughly southwest–northeast direction for about 140 kilometers (87 mi),[5] with the Adycha at its northern end.

The highest peak is a 1,926 metres (6,319 ft) high unnamed summit.

[6] The smaller Tirekhtyakh Range, another subrange of the Chersky Mountains, rises to the north, stretching parallel to the general direction of the Nelgesin Range.
