Muchu Chhish (7,453 metres (24,452 ft)) is a mountain in the Batura Muztagh sub-range of the Karakoram in Hunza Valley, in northern areas of Pakistan. Located in a very remote and inaccessible region, only a handful of attempts have been made to reach the summit. Muchu Chhish was one of the tallest unclimbed mountains on Earth, until its successful summit in 2024. The peak has a modest prominence however, rising only 263 m (863 ft) above the nearest col or pass. The Batura Glacier, one of the longest outside the polar regions, flanks Muchu Chhish to the north.

Muchu Chhish lacks any well-defined northern or southern ridges of its own and is nearly impassable from the north due to glacial icefall; most expeditions thus attempt it via the South Ridge of 7,462 m (24,482 ft) Batura VI to the immediate west. This ridge was climbed by a Polish expedition in 1983 using fixed ropes while making the first ascent of 7,531 m (24,708 ft) Batura V and VI. One attempt was by a Spanish expedition in 1999, which reached 6,650 m (21,820 ft) on the south ridge. In 2020, a three-member Czech expedition, including climber Pavel Kořínek and former politician Pavel Bém, made an attempt, but they did not reach the top due to bad weather. The same climbers tried again in 2021, but that attempt failed due to excessive amounts of snow on the ridge.

A Czech team consisting of Zdenek Hak, Radoslav Groh, and Jaroslav Bansky reached the summit of Muchu Chhish on July 5, 2024 after a six day climb. At the time of the summit, it was the highest unclimbed peak in the Karakoram.
