Doi Suthep–Pui National Park (Thai: อุทยานแห่งชาติดอยสุเทพ-ปุย) is a national park in Chiang Mai Province in Thailand. It includes Wat Phra That Doi Suthep, a Buddhist temple, and Bhubing Palace, the winter residence of the Thai royal family. The park is a protected area for flora, fauna, and habitat.

The former name of the area is Doi Aoi Chang. The name Doi Suthep was inspired by a hermit named Prarusiwa Suthep who once lived in the local forest. In 1973, the Royal Forest Department proposed that this and 13 other forests be designated national parks. It became the 24th national park of Thailand when it was official established on 14 April 1981. Today it includes 160,812 rai ~ 257 square kilometres (99 sq mi) of territory.

The mountainous landscape is part of the Thanon Thong Chai Range. The three main peaks are Doi Suthep, Doi Buak Ha, and Doi Pui, the latter of which is tallest at 1,685 metres (5,528 ft). The climate is cool, with an average temperature around 20 to 23 °C (68 to 73 °F). Low winter temperatures can reach 6 °C (43 °F). Late summer is the rainy season, with daily precipitation.

More than 2,000 species of vascular plants have been documented in the national park.

The park is forested, with evergreen forest above 1,000 metres (3,300 ft) and deciduous forest below. Mixed deciduous-evergreen forest occurs in gullies and along streams. Common trees include oaks, dipterocarps, and trees of the magnolia family. There are many waterfalls.

The forests in the park are divided into two main types of forests. Deciduous forests are found up to about 900-1,000 meters above sea level, while lower montane evergreen forests are found starting from about 900-1,000 meters above sea level.

The dipterocarp deciduous forest is primarily composed of Dipterocarpus tuberculatus, Dipterocarpus obtusifolius, Shorea siamensis, and Shorea obtusa. The oak species Quercus kerrii is also found in the deciduous forest. Other major non-dipterocarp tree species in the deciduous forest are Pterocarpus macrocarpus, Xylia xylocarpa, Terminalia mucronata, Terminalia alata, and Vitex peduncularis.

The pine tree Pinus kesiya is found at higher elevations.

The montane evergreen forest primarily consists of Schima wallichii, Castanopsis acuminatissima, Castanopsis tribuloides, Magnolia baillonii, Magnolia garrettii, among other tree species. Tectona grandis and Cassia fistula used to be common, but are no longer widely found due to centuries of logging.

The park is home to diverse fungi species, many of which may be undescribed or have only been recently described.

Fungi in the park primarily belong to the families Boletaceae, Agaricaceae and Russulaceae. A 2007 survey found 30 species of ascomycetes and 228 species of basidiomycetes in the forests surrounding Chiang Mai city.

Different species and genera tend to occupy different ecological niches:

• dry dipterocarp forests: Russula, Boletus, and Amanita
• wet dipterocarp forests: Amanita, Lactarius, and Russula
• pine forests: Lactarius and Amanita
• oak forests: Russula, Lactarius, Amanita, and Boletus

Mushrooms belonging to the genera Astraeus, Heimiella, Pterygellus, and Mycoamaranthus are also found in the park.

Dozens of wild fungi species are locally harvested for human consumption. Mushrooms are often collected from dipterocarp forest floors during the rainy season from June to October. They include:
