Changtse, Mountain peak in Shigatse, China.

Changtse is a 7,543-metre peak in the Mahalangur Himal of Tibet, standing immediately north of Mount Everest and joined to it by the North Col at 7,020 metres. It closes the Kangshung valley to the northwest and is the world's 45th-highest mountain. Its Changtse Glacier flows north into the East Rongbuk Glacier.

The first permitted ascent took place on October 14, 1982, when five members of a German expedition reached the summit via the Northeast Ridge. This success marked the opening of an alternative climbing route to the Everest massif.

The Tibetan name བྱང་རྩེ (Changtse) means "north peak", and the Chinese form is 章子峰 (Zhāngzi fēng). The peak closes the Kangshung valley on the northwest, a valley bounded to the south by Everest, Lhotse, Chomolonzo and Makalu. In 2013 a Red Bull expedition led by BASE jumper Valery Rozov reached 7,200 m below the summit; Rozov jumped in a wingsuit and landed on the Rongbuk Glacier, then the highest BASE jump ever made.

Climbers can access the mountain via the North Col route or directly from the East Rongbuk Glacier, with steep rock sections requiring technical climbing skills. Weather conditions are unpredictable at this elevation, so proper preparation and local guidance are essential.

On 5 May 2013 a Red Bull expedition led by BASE jumper Valery Rozov reached 7,200 metres below Changtse's summit. Rozov jumped in a wingsuit and landed on the Rongbuk Glacier, the highest BASE jump made anywhere at that time.
