Doi Phu Nang National Park is a national park in Dok Khamtai, Pong and Chiang Muan Districts, Phayao Province, Thailand. It is located in two mountain chains of the Phi Pan Nam Range, Mae Yom and Nampi, with a unprotected area in between. There are both mixed evergreen forests, dipterocarp forest and dry deciduous forests in the park area. Doi Phu Nang, the mountain that gives its name to the park, with an altitude of 1,202 m, is the highest peak in the area. The sources of two tributaries of the Yom River are in this mountain range. The park also has scenic rock formations and two impressive waterfalls, Namtok Than Sawan and Namtok Huai Ton Phueng.
The park is rich in both flora and fauna. A variety of birds are found, especially the rare green peafowls, threatened by habitat destruction, which come to the park area for breeding from January to March. Among the other animals, the fishing cat, Asiatic black bear, muntjac, masked palm civet, bamboo rat, tree shrews, the Asiatic softshell turtle and the Bengal monitor deserve mention.
