Gasherbrum III

Gasherbrum III simplified Chinese: 加舒尔布鲁木III峰; traditional Chinese: 加舒爾布魯木III峰; pinyin: Jiāshūěrbùlǔmù III Fēng), surveyed as K3a, is a summit in the Gasherbrum massif of the Baltoro Muztagh, a subrange of the Karakoram on the border between Xinjiang, China and Gilgit-Baltistan, Pakistan. It is situated between Gasherbrum II and IV.

Gasherbrum III fails to meet a 500-metre topographic prominence cutoff to be an independent mountain; hence it can be considered a subpeak of Gasherbrum II.

Gasherbrum III was one of the highest unclimbed summits in the world up to its first ascent in 1975, by Wanda Rutkiewicz, Alison Chadwick-Onyszkiewicz, Janusz Onyszkiewicz and Krzysztof Zdzitowiecki, members of a Polish expedition.
