Tahu Rutum is a peak and is nearby to Great Karakoram, Muztagh and Kanjut Sar. Tahu Rutum has an elevation of 6,650 metres.
The Tahu Rutum forms a spectacular rock tower on the border of the glacial areas of the Biafo, Hispar and Khurdoping glaciers. It is located in the extreme southeast of Hispar Muztagh, part of the Karakorum main chain in the autonomous region of Gilgit-Baltistan in Pakistan. The mountain is dewatered to the north by the Western Khurdoping Glacier, to the west by the Eastern Khani Basa Glacier, and to the south by the Tahu Rutum Glacier, a western tributary glacier of the Lukpe Lawo (Snow Lake). To the west, a ridge leads to 6.46 km west-northwestern Kanjut Sar II. To the east is the 5670 m high West Khurdopin Pass and beyond this the Lukpe Lawo Brakk (6593 m).
The Tahu Rutum was first climbed in 1977 by a Japanese expedition.  On July 13, Kazuto Obata, Yukio Usagawa, Yoshinobu Tanaka and Kazuya Mitsumochi reached the summit.  The ascent route led from the southeast over the southwest ridge to the summit.
In 2008, the US American Kyle Dempster tried a solo pass through the west wall
