Loenpo Gang, Mountain summit in Rasuwa, Nepal.

Loenpo Gang is a mountain summit along the border between Nepal and the Tibet Autonomous Region, rising to 6,979 meters above sea level. The peak sits within the Langtang range and overlooks the Rasuwa valley below.

Japanese mountaineers Tadashi Morita and Kazunari Yasuhisa made the first successful ascent in 1962. This achievement marked an important moment in the exploration of peaks along this remote border region.

Loenpo Gang is also called Big White Peak, a translation of its Tibetan name. The mountain lies at the eastern edge of Langtang National Park, near the Langtang Khola valley, and the Nyanang-Phu glacier runs along its north flank. Its Nepali side falls in Bagmati province, and the summit line forms the border with Tibet.

Loenpo Gang lies in the far east of Langtang National Park, on the Nepal–Tibet border in Bagmati zone; the approach runs through Rasuwa. The Nyanang Phu glacier flows along the north flank, so the south wall and east ridge, the line of the 1962 first ascent, are the usual objectives. The nearest roadheads lie below the Langtang Khola valley, and the peak stands 17 km south of Shishapangma.

The German name Big White Peak refers to the mountain's appearance. Shishapangma, one of the eight-thousanders, lies 17 km to the north, while the Nyanang Phu glacier flows along the north flank toward the southeast.
