The Common Treeshrew Tupaia glis occurs in southern Thailand and Peninsular Malaysia, including the larger islands of both countries, Singapore, and the islands of Bintan and Batam the Riau Archipelago of Indonesia.

To the north of its range it is replaced by the Northern Treeshrew Tupaia belangeri.

It inhabits primary forest and various grades of secondary forest, and locally can adapt to parklands. It is active by day, either on the forest floor or amongst low vegetation and fallen branches, where it feeds on insects and fallen fruit.

Its fur colour is variable; specimens from lower montane habitat at Fraser's Hill, Peninsular Malaysia are brown (Fig. 1), in Singapore it is brown to reddish-brown, with sub-adults of orange-brown (Fig. 3), and on Bintan Island is reddish-brown (Fig. 4). There is a narrow, pale stripe on each shoulder.
