Agathis borneensis or more commonly known as damar minyak in Malay, is a big, lightweight softwood tree which belongs to the family Araucariaceae. It can grow up to 42 m tall with about 95 cm in diameter. The inner bark is light red to reddish-brown. The leaves are opposite and measured around 7.2-11.3 cm long x 2.5-4 cm wide. The mature pollen cones are more than 1.7 cm wide, while the microsporophyll is spoon-shaped. The seed cones are dark reddish-brown to black and ovoid to ellipsoid in shape while the seeds are oblique and obovate in shape which measured around 15 x 12 mm.

The genus derived from a Greek word, agathis means a clew, corner of a sail, and this may refer to the leaf shape; meanwhile the species epithet means from Borneo.

It is distributed in Sumatra, Peninsular Malaysia and throughout Borneo. It occurs in lowland to lower montane forest and in sandy heath forest. The conservation status of this tree is near threatened in Peninsular Malaysia but it is listed as an endangered species in the IUCN Red List. This is due to the deforestation and targeted logging in recent decades, and this tree is often found in production areas of forest reserves (Lim, 2010; IUCN, 2013).
