The chipmunk is rodent among all these animals. Chipmunks are small, striped rodents of the family Sciuridae. Chipmunks are found in North America, with the exception of the Siberian chipmunk which is found primarily in Asia. Chipmunks may be classified either as a single genus, or as three genera: Tamias, which includes the eastern chipmunk; Eutamias, which includes the Siberian chipmunk; and Neotamias, which includes the 23 remaining, mostly western, species.
These classifications are arbitrary, and most taxonomies over the twentieth century have placed the chipmunks in a single genus. The genus name Tamias is Greek for "treasurer", "steward", or "housekeeper", which is a reference to the animals' role in plant dispersal through their habit of collecting and storing food for winter use.
