The 2008 K2 disaster occurred on 1 August 2008, when 11 mountaineers from international expeditions died on K2, the second-highest mountain on Earth. Three others were seriously injured. The series of deaths, over the course of the Friday ascent and Saturday descent, was the worst single accident in the history of K2 mountaineering. Some of the specific details remain uncertain, with different plausible scenarios having been given about different climbers' timing and actions, when reported later via survivors' eyewitness accounts or via radio communications of climbers who died later in the course of events on K2 that day.

K2, at 8,611 metres (28,251 ft) above sea level, is the second-highest mountain on Earth, after Mount Everest at 8,849 metres (29,032 ft). It lies in the Karakoram range, partially in the Gilgit-Baltistan region of Pakistan-administered Kashmir and partially in the China-administered Trans-Karakoram Tract in the Taxkorgan Tajik Autonomous County of Xinjiang.
