Kinthup, a Lepcha man from Sikkim, was an explorer in the area of Tibet in the 1880s. He is best known for his impressive devotion to duty in surveying a previously unknown area of Tibet.

The Lepcha are among the indigenous peoples of the Indian state of Sikkim and Nepal, and number around 80,000. Many Lepcha are also found in western and southwestern Bhutan, Darjeeling, the Koshi Province of eastern Nepal, and in the hills of West Bengal. The Lepcha people are composed of four main distinct communities: the Renjóngmú of Sikkim; the Dámsángmú of Kalimpong, Kurseong, and Mirik; the ʔilámmú of Ilam District, Nepal; and the Promú of Samtse and Chukha in southwestern Bhutan.
