The Ulakhan-Bom (Russian: Улахан-Бом; Yakut: Улахан Бом, meaning "Big Obstacle")[1] is a range of mountains in far North-eastern Russia, a southern prolongation of the Verkhoyansk Range, part of the East Siberian System.

The urban locality of Solnechny is located near the slopes of the range, by the Allakh-Yun River.

The smaller Kyllakh Range rises west of the Khanda valley, in the southwestern side of the Ulakhan-Bom, between the Aldan and the southern section of its western slopes.

The highest point of the mountain chain is an unnamed 1,830 metres (6,000 ft) high peak rising above the left bank of the Allakh-Yun river.

Thickets of Siberian pine and mountain tundra grow at elevations above 1,000 metres (3,300 ft).
