Gasherbrum I (Urdu: گاشر برم -1; simplified Chinese: 加舒尔布鲁木I峰; traditional Chinese: 加舒爾布魯木I峰; pinyin: Jiāshūěrbùlǔmù I Fēng), also known as Hidden Peak or K5, is the 11th highest mountain in the world at 8,080 metres (26,510 ft) above sea level. It is located on the Pakistani–Chinese border in Gilgit–Baltistan region of Pakistan and Xinjiang region of China. Gasherbrum I is part of the Gasherbrum massif, located in the Karakoram region of the Himalaya. Gasherbrum is often claimed to mean "Shining Wall", presumably a reference to the highly visible face of the neighboring peak Gasherbrum IV; but in fact it comes from "rgasha" (beautiful) + "brum" (mountain) in Balti, hence it actually means "beautiful mountain."
Gasherbrum I was designated K5 (meaning the 5th peak of the Karakoram) by T.G. Montgomerie in 1856 when he first spotted the peaks of the Karakoram from more than 200 km away during the Great Trigonometric Survey of India. In 1892, William Martin Conway provided the alternate name, Hidden Peak, in reference to its extreme remoteness.
Gasherbrum I was first climbed on July 5, 1958 by Pete Schoening and Andy Kauffman of an eight-man American expedition led by Nicholas B. Clinch. Richard K. Irvin, Tom Nevison, Tom McCormack, Bob Swift and Gil Roberts were also members of the team.

- 1958 - An American team makes the first ascent.
- 1975 - Reinhold Messner and Peter Habeler reached the summit on a new route (northwest route) in pure alpine style (first time on an 8000-metre peak) taking three days total. One day later, a team of three led by Austrian Hanns Schell reached the summit on the American route.
- 1977 - The fourth successful ascent by two Slovenians (Nejc Zaplotnik and Andrej Stremfelj), again on a new route.

Her husband, Sylvain Saudan from Switzerland, performs the first ski descent from the top of an 8000-metre peak to base camp.
- 1983 - Jerzy Kukuczka with Wojciech Kurtyka, new route. Alpine style ascent without the aid of oxygen.

- 2012 - March 9, Adam Bielecki and Janusz Gołąb made the first winter ascent. The ascent was made without the aid of supplementary oxygen. The same day, three climbers from a different expedition — Austrian Gerfried Goschl, Swiss Cedric Hahlen and Pakistani Nisar Hussain Sadpara — went missing, never to be found again. They were trying to ascend via a new route and are considered to have been blown off by strong winds.
