The eastern chipmunk (Tamias striatus) is a chipmunk species found in eastern North America. It is the only living member of the chipmunk subgenus Tamias, sometimes recognized as a different genus. The name "chipmunk" comes from an Ojibwe word which translates literally as "one who descends trees headlong." First described by Mark Catesby in his 1743 The Natural History of Carolina, Florida, and the Bahama Islands, the chipmunk was eventually classified as Sciurus striatus by Linnaeus, meaning "striped squirrel" in Latin.
