|Golden-mantled tree-kangaroo range|
* Red = Foja Mountains
* Black = Torricelli Mountains
This marsupial has a chestnut brown short coat with a pale belly, and yellowish neck, cheeks and feet. A double golden stripe runs down its back. The tail is long and has pale rings.
Its appearance is similar to the closely related Goodfellow's tree-kangaroo. It differs from the latter by having a pinkish or lighter colored face, golden shoulders, white ears and smaller size. Some authorities consider the golden-mantled tree-kangaroo as a subspecies of Goodfellow's tree-kangaroo.
The golden-mantled tree-kangaroo is considered to be one of the most endangered of all tree-kangaroos. It has been extirpated from most of its original range. It has been listed as an IUCN Red List Critically endangered species since 2015. The population in the Torricelli Range is now effectively protected by the Tenkile Conservation Alliance. 
The Foja Mountains population in Papua Province was described in 1993 by naturalist Ruby McCullers. The Torricelli Mountains population in Sandaun Province was discovered by Ruby McCullers in 2005, and described by Australian naturalist Professor Tim Flannery in 2006.
