Jianan Pass (Chinese: 加南达坂; pinyin: Jiā nán dá bǎn) is a mountain pass in the eastern Karakoram Range near the Chang Chenmo Valley. The Line of Actual Control (LAC) between India and China runs through the pass dividing the Indian-administered Ladakh and Chinese-administered Aksai Chin. The pass lies on the watershed between Kugrang and Galwan river basins. The Changlung river basin is also immediately to the east of the pass. While China uses the name "Jianan Daban" for the pass, India refers to it as Patrol Point 15 (PP-15) for border security purposes. The term "Hot Springs" has also been used by Indian media through misapplication of terminology.

The region around the pass is part of the Sino-Indian border dispute. China advanced its border claims between 1956 and 1960, eventually claiming the Galwan river basin to the north of the pass, while India continued to claim the entire Aksai Chin plateau. India set up an advance post to the north of the Jianan Pass in 1962, near the Galwan Valley, which caused an "apogee of tension". During the 1962 war, China attacked the post and eliminated it, enforcing its territorial claims.

During the 2020–2022 skirmishes, the area around the pass was again a scene of contest. The standoff was finally resolved in September 2022, with a disengagement formula agreed.

South of Galwan Valley, the Karakoram range divides into multiple branches. The western branch lies between the Shyok River valley and the Kugrang valley, the middle branch between the Kugrang and Changlung valleys, and the eastern branch to the east of the Changlung valley. The Kugrang river flows southeast within the territory under present Indian control, joining the Chang Chenmo River near Hot Springs (also called Kyam or Kayam). The Changlung river flows in a parallel valley to the northeast in territory under present Chinese control, but eventually joins the Kugrang river near Gogra.

The Kugrang Valley extends further northwest than the Changlung Valley, interacting with the Galwan river basin to the north. The Jianan Pass lies on the watershed between Kugrang and Galwan basins. It is a relatively low pass, at an elevation of 5350 metres, and the ascent on both the sides is gradual. To the south of Jianan pass lies a 15 km-long tributary of the Kugrang River. To the north of the pass is a small stream, which joins a tributary of Galwan called Shimengou (Chinese: 石门沟; pinyin: Shímén gōu), flowing into the Galwan River 8 km downstream.

The Kugrang Valley was little explored during the British Raj. Survey maps show survey stations having been established near the Chang Chenmo Valley. So the Kugrang Valley was only surveyed from a distance, with the results being quite approximate. The Kugrang valley did form a popular hunting area for British officers vacationing in Ladakh.

After India became independent in 1947 and China took control of Tibet in 1950, both the countries laid claim to the Aksai Chin plateau. In its 1956 border definition, China claimed Lingzithang Plains up to the campsite of Samzungling in the upper Galwan Valley. The majority of the eastern Karakoram range was left in India, including the Galwan Valley to the west of Samzungling and the entire Changlung valley. (Map 3)

Not recognising Chinese claims to Aksai Chin, India continued to send border patrols in "all directions". A common patrol route was along the Changlung Valley and Samzungling to the northern periphery of Aksai Chin. In 1959, a police party sent to set up police posts in these valleys was confronted by Chinese troops near Kongka La and a serious clash occurred, called the Kongka Pass incident.
