Callosciurus is a Southeast Asian genus of squirrels. Several of the species have settled on small islands, and have developed separate subspecies. In total, the genus contains 14 species and up to 300 subspecies or varieties. The genera Glyphotes, Rubrisciurus, and Tamiops are sometimes also included in Callosciurus.

Several species are very colourful; in fact, they belong to the most colourful mammals. The Pallas's squirrel has an unremarkable olive green back, but its belly is bright red. The "typical" subspecies of Prevost's squirrel have a black back, white sides, and red-brown underside. The Finlayson's squirrel occurs in numerous varieties, three of which are red-brown, black, and pure white. The length of these squirrels is between 15 y 25 cm (5,9 y 9,8 plg), not including the 8 a 25 cm (3,1 a 9,8 plg) long tail.

Most squirrels in Callosciurus live in tropical rain forests, but some individuals live in parks and gardens in Southeast Asian cities. In the trees, they build their nests out of plant material. The are solitary, and give birth to one to five young. Their food consists of nuts, fruits, and seeds, and also of insects and bird eggs.
