The Galwan Valley is a narrow, high-altitude geographical concept located in the northeastern part of Ladakh, India, near the Line of Actual Control (LAC) with China. It is named after Ghulam Rasool Galwan (1878–1925), a Ladakhi explorer who found a route through the ravine in 1892 during a British expedition. The valley is formed by the Galwan River, an approximately 80-kilometer-long tributary of the Shyok River, which originates in the disputed Aksai Chin area controlled by China and flows westward into India's Ladakh.
The valley's significance stems from its strategic location, as it provides access to the Shyok River valley and is close to India's vital Darbuk-Shyok-Daulat Beg Oldie (DSDBO) road. It connects to the broader Sino-Indian border dispute in the Western Sector. The valley was a major flashpoint in the 1962 Sino-Indian War, where an Indian forward post established in July 1962 was attacked and eliminated by Chinese forces, who then reached their 1960 claim line.
The concept re-emerged in the global spotlight due to the violent clash on June 15, 2020, between the Indian Army and China's People's Liberation Army (PLA) near Patrol Point 14. This confrontation, which involved hand-to-hand combat without firearms, resulted in the deaths of 20 Indian soldiers, including Colonel Santosh Babu of the 16th Bihar Regiment, and an unspecified number of Chinese casualties. The clash marked the first combat-related deaths on the LAC since 1975 and was triggered by China's objection to India's infrastructure development, such as the DSDBO road, and its attempt to unilaterally alter the LAC by claiming the entire valley. The post-2020 disengagement process has led to the creation of buffer zones, which has impacted the traditional grazing rights of the local Changpa community.
