The Tirekhtyakh Range (Russian: Тирехтяхский хребет; Yakut: Тирэхтээх)[2][3] is a mountain range in the Sakha Republic (Yakutia), Far Eastern Federal District, Russia.

[1] The Tirekhtyakh Range rises in the area of the Yana-Oymyakon Highlands, part of the Chersky Mountains, to the west of the Adycha, south of the Borulakh and north of the Nelgese.

[1] It stretches in a roughly southwest–northeast direction for about 130 kilometers (81 mi),[5] with the Adycha bending westwards at its northern end.

The highest peak is a 1,816 metres (5,958 ft) high unnamed summit.

[6] The slightly larger and higher Nelgesin Range, another subrange of the Chersky Mountains, rises to the south, stretching roughly parallel to the general direction of the Tirekhtyakh Range.
