The Karakoram 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.

The Karakoram is home to the highest concentration of peaks over 8000m in height to be found anywhere on earth, including K2, the second highest peak of the world 8,611 m (28,251 ft).

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 kilometres (43 mi) and the Biafo Glacier at 63 kilometres (39 mi) rank as the world’s second and third longest glaciers outside the Polar Regions. Some of the debris-covered Karakoram glaciers are found to be expanding but other ones are retreating.

The Karakoram is bounded on the northeast by the edge of the Tibetan Plateau, and on the north by the Pamir Mountains. The southern boundary of the Karakoram is formed, west to east, by the Gilgit, Indus, and Shyok Rivers, which separate the range from the northwestern end of the Himalaya range proper as these rivers converge southwestward towards the plains of Pakistan.
