Pangong Lake, situated at a breathtaking altitude of around 4,350 meters (14,270 feet), straddles the international border between India and Tibet (now controlled by China). The lake is located in the Ladakh region of the Indian union territory of Ladakh and extends from India to the Tibetan Autonomous Region of China.

The history of Pangong Lake is intertwined with the geopolitical dynamics of the region. While the lake itself has existed for millennia, its significance in the modern context emerged during the 20th century.
