The Karakoram, or Karakorum (simplified Chinese: 喀喇昆仑山脉; traditional Chinese: 喀喇崑崙山脈; pinyin: Kālǎkūnlún Shānmài; Hindi: काराकोरम, Kārākōrama; Urdu: سلسلہ کوہ قراقرم), is a large mountain range spanning the borders between Pakistan, India and China, located in the regions of Gilgit–Baltistan (Pakistan), Ladakh (India), and Xinjiang region, (China). It is one of the Greater Ranges of Asia, a part of the greater Himalaya while north of the actual Himalaya Range.

The Karakoram is home to the highest concentration of peaks over eight kilometres (five miles) in height to be found anywhere on earth, including K2, the second highest peak of the world (8,611 m/28,251 ft). K2 is just 237 m (778 ft) lower than the 8,848 m (29,029 ft) tall Mount Everest.

The range is about 500 km (311 mi) in length, and is the most heavily glaciated part of the world outside the polar regions. The Siachen Glacier at 70 km and the Biafo Glacier at 63 km rank as the world's second and third longest glaciers outside the polar regions.
