The thick-tailed pygmy jerboa (Salpingotus crassicauda) is a species of rodent in the family Dipodidae.

The head is large and the eyes small, the ears are short and tubular and the tail may have a thickening near the base where fat is deposited.

This jerboa feeds on small invertebrates such as grasshoppers and spiders and also some vegetable matter, mostly seeds.

[1] The thick-tailed pygmy jerboa varies in its spatial distribution and its populations are subject to large fluctuations.

Threats it faces include predators, droughts, overgrazing of its habitat, destruction of its burrows and road kill.
