Labuche Kang III/East, Unclimbed mountain peak in Tingri County, Tibet Autonomous Region, China.

Labuche Kang III/East is a glaciated peak of 7,250 m in the Lapche Himal, on the Labuche Kang massif in Tingri County, Tibet. It lies 3.17 km east of its parent, Labuche Kang (7,367 m), and has a prominence of 570 m. A 10 km glacier flows north from the mountain into a high mountain lake, and a sub-peak, East Labuche Kang II (7,040 m), stands about a mile to the east.

Labuche Kang III was long listed as one of the highest unclimbed peaks, second only to Gangkhar Puensum until Saser Kangri II East was climbed on 24 August 2011. A Japanese expedition attempted the summit in 2018 but failed. The mountain lies 3.17 km east of its parent, Labuche Kang, in Tingri County.

The peak lies in Tingri County, where the Labuche Kang massif is entirely glaciated; a 10 km glacier flows north from the mountain into a high mountain lake. The massif's name is shared with the parent peak 3.17 km to the west, and the mountain is also called Labuche Kang East.

Labuche Kang III lies in Tingri County, Tibet, about 3.17 km east of its parent Labuche Kang, with a 10 km glacier flowing north from the massif into a high mountain lake. A sub-peak, East Labuche Kang II (7,040 m), stands roughly a mile east of the main summit. Approach logistics must account for this remote, glaciated terrain.

A sub-peak called East Labuche Kang II, 7,040 m high with 180 m of prominence, lies about a mile east of the main summit. The German sources instead record a 7,020 m western sub-peak 1.11 km to the northwest. A 10 km glacier flows north from the mountain into a high mountain lake.
