Dipterocarpus dyeri (Khmer: rôyiëng, chhë tiël pruhs, chhë tiël th'nô:r,^[1] local name Kompong Thom: chhieutiel chgor,^[2] name used for commercial timber and the group of trees harvested for such: keruing, Vietnamese: dau song nang,^[3] is a species of tree in the family Dipterocarpaceae found in Myanmar, Thailand, Peninsular Malaysia (Kedah, Perlis), Cambodia and Vietnam.^[4][5] The tree is found in lowland semi-evergreen dipterocarp forests and Schima/bamboo forests,^[4] an alternative habitat description is mixed dense forests of the plains, mainly among rivers and valleys.^[1] The tree is a climax or late successional species, which in some secondary forests forms relatively young pure colonies^[6] . The conservation status is based on rates of habitat loss, the major threat to the taxa,^[4] though in Vietnam it is cited as having a less threatened conservation status of Vulnerable.^[3]

In Cambodia the wood is classified as of the 2nd best category, and is in great demand for house and boat construction.^[1]

The following insects are associated with and prey on the seed of D. costatus: Alcidodes, particularly Alcidodes crassus (Pascoe, 1882), Pempelia, Salebria, Dichocrocis, Andrioplecta pulverula Meyrick, and Andrioplecta shoreae Komai^[7]
