Dipterocarpus turbinatus (Khmer chhë tië:l dâ:ng;[3] India gurjan,[4] gurjun,[4] gurgina; Tagalog mayapis;[5] Chinese 羯布罗香 jie bu luo xiang;[6] Malay language keruing,[4] the last an international name for Dipterocarpus wood) is a species of tree in the family Dipterocarpaceae native to north-eastern India and mainland Southeast Asia, and cultivated in surrounding regions.

[1] It is cultivated in Indonesia (Sumatra, Java, Kalimantan), Philippines, and China (southeast Tibet, southern & western Yunnan).

The ovary is densely pubescent; style terete, silvery gray tomentose on lower half.

The conservation status is based on the rate of habitat loss, the major threat for the species, though some subpopulations are protected in reserves.

In herbal medicine, the plant has been traditionally used for treating gonorrhea, leprosy, psoriasis, and other skin diseases.
