Dipterocarpus condorensis

Dipterocarpus condorensis is a species of plant in the evergreen or semi-evergreen family Dipterocarpaceae.

It is an emergent tree, up to 50 m tall, in mixed dipterocarp forest on dry ridges. It is found in Sumatra, coastal Peninsular Malaysia, Singapore, and Borneo, the Philippines, and Vietnam. It is a medium hardwood sold under the trade names of Keruing. It was formerly most abundant along the coastal hills on sandy soils, but is endangered due to land conversion. D. condoriensis is found in at least one protected area (Sepilok Forest Reserve).

There are two accepted subspecies:

• Dipterocarpus condorensis subsp. condorensis (synonym Dipterocarpus caudatus <small>Foxw.</small>) – Vietnam (Con Dao) and Philippines (Luzon and Mindanao)

The synonymous species name caudatus is derived from Latin (' = tailed) and refers to the narrow of the leaf apex.
