Gasherbrum I (; ), surveyed as K5 and also known as Hidden Peak, is the 11th highest mountain in the world at above sea level. It is located in Gilgit-Baltistan region of Pakistan . 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.
