Eutamias is a genus of chipmunks within the tribe Marmotini of the squirrel family. It includes a single living species, the Siberian chipmunk (Eutamias sibiricus). The genus is often treated as a subgenus of Tamias, which is now restricted to the eastern chipmunk of North America.[1] Neotamias, which now includes the western North American chipmunks, has also been included in Eutamias.[2]
In addition to the Siberian chipmunk, several fossil species have been assigned to this genus:
