Colonel Narendra Kumar, PVSM, KC, AVSM, FRGS was an Indian soldier and mountaineer. He is known for his expeditions across various mountain ranges such as the Himalayas and Karakorams, and respective subranges such as the Pir Panjals and Saltoro Mountains. His reconnaissance efforts on the Siachen glacier were key to the Indian Army's reclamation of the forward posts of the glacier in Operation Meghdoot in 1984. He was the deputy leader of the first successful Indian Mount Everest expedition in 1965.

The Siachen Glacier is a glacier located in the eastern Karakoram range in the Himalayas at about 35.421226°N 77.109540°E, just northeast of the point NJ9842 where the Line of Control between India and Pakistan ends. At 76 km (47 mi) long, it is the longest glacier in the Karakoram and second-longest in the world's non-polar areas. It falls from an altitude of 5,753 m (18,875 ft) above sea level at its head at Indira Col on the India–China border down to 3,620 m (11,875 ft) at its terminus. The entire Siachen Glacier, with all major passes, has been under the administration of India as part of the union territory of Ladakh, located in the Kashmir region since 1984. Pakistan maintains a territorial claim over the Siachen Glacier and controls the region west of Saltoro Ridge, lying west of the glacier, with Pakistani posts located 1 km below more than 100 Indian posts on the ridge.
