The Shansei vole (Craseomys shanseius) is a species of rodent in the family Cricetidae.

The Shansei vole was first described in 1908 as Myodes shanseius by the British zoologist Oldfield Thomas, the type locality being Chao Cheng Shan in Shanxi Province.

[1] However the molar teeth in adults do not have roots which sets it apart from that species and tends to associate it with Eothenomys species, though the fur length, texture and colour pattern are more like Craseomys and Clethrionomys than Eothenomys.

Its diet consists mainly of grasses, green leaves and stems, and to a lesser extent it feeds on seeds.

[3] The Shansei vole has a wide range and is assumed to have a large total population.
