Dudipatsar Lake or Dudipat Lake is a lake encircled by snow clad peaks in Lulusar-Dudipatsar National Park. The lake lies in the extreme north of the Kaghan Valley, in the Mansehra District, Khyber Pakhtunkhwa province, in northern Pakistan. The word "dudi" means white, "pat" means mountains and "sar" means lake. This name has been given to the lake because of the white color of snow at surrounding peaks. In summer the water of the lake reflects like a mirror. The word "sar" is used with the name of each lake in the area, translating as 'lake.'

The lake's water is a beautiful greenish blue hue and very cold, at an elevation of 3,800 metres (12,500 ft). The surrounding mountains, with snow patches in the shady dales, average around 4,800 metres (15,700 ft) in elevation. Their natural habitat is in the Western Himalayan alpine shrub and meadows ecoregion. The lake and its wetlands habitats are of significant ecological importance for resident fauna and migratory waterfowl. Some of the park's fauna includes the snow leopard, black bear, marmot, weasel, lynx, leopard, Himalayan snowcock, and snow partridge.

Lulusar Lake, also in the park, is the primary headwaters of the Kunhar River. Saiful Muluk National Park, with Saif ul Maluk Lake, is adjacent in the 150 kilometres (93 mi) long Kaghan Valley region and together the parks protect 88,000 hectares (220,000 acres).
