Chisocheton tomentosum is a rainforest tree of the Malay Peninsula and Sumatra belonging to the family Meliaceae.

It is a rarely branching, pachycaulous tree up to seventy feet (twenty-one metres) in height, but rarely exceeding eight inches (twenty centimetres) in diameter at breast height (DBH).

It has a symbiotic relationship with certain unspecified species of ants (myrmecophily).

The once-pinnate, indeterminate leaf blades (laminae) are up to 6 feet 7 inches (2 m) in length in rosettes at the top of the trunk and the few vertical branches (reiterations), with additionally a stalk (petiole) of eight inches (twenty centimetres).

There are separate male and female trees (dioecious).
