Hagen's flying squirrel (Petinomys hageni) is a species of rodent in the family Sciuridae. It is endemic to Indonesia.
Flying squirrels are a tribe of 50 species of squirrels in the family Sciuridae. Despite their name, they are not in fact capable of full flight in the same way as birds or bats, but they are able to glide from one tree to another with the aid of a patagium, a furred skin membrane that stretches from wrist to ankle. Their long tails also provide stability as they glide. Anatomically they are very similar to other squirrels with a number of adaptations to suit their lifestyle; their limb bones are longer and their hand bones, foot bones, and distal vertebrae are shorter. Flying squirrels are able to steer and exert control over their glide path with their limbs and tail.
Sciurinae is a subfamily of squirrels, uniting the flying squirrels with certain related tree squirrels. Older sources place the flying squirrels in a separate subfamily (Pteromyinae) and unite all remaining sciurids into the subfamily Sciurinae, but this has been strongly refuted by genetic studies.

It is found in forests in Peninsular Malaysia, Singapore, Sumatra and Borneo. This peculiar, terrestrial squirrel mainly feeds on insects and earthworms. It quite closely resembles a Tupaia treeshrew in appearance, but the shrew-faced squirrel can be recognized by its shorter gape, and shorter and more bushy tail.
