The Rio Grande ground squirrel (Ictidomys parvidens) is a species of squirrel in the family Sciuridae.

All the species of Ictidomys were previously believed to belong to the much larger genus Spermophilus (I. parvidens as a subspecies of Spermophilus mexicanus),[1] but DNA sequencing of the cytochrome b gene showed that this group was paraphyletic to the prairie dogs and marmots,[2] and could therefore no longer be retained as a single genus. As a result, Ictidomys is now considered as a genus in its own right.[3]
