The Colorado chipmunk (Neotamias quadrivittatus) is a species of chipmunk in the squirrel family Sciuridae. It is endemic to Colorado, Utah, Arizona and New Mexico in the United States.

N. q. australis - Organ Mountains, New Mexico N. q. oscuraensis - Oscura Mountains, New Mexico N. q. quadrivittatus - Colorado, northern New Mexico, northern Arizona, eastern Utah The Colorado chipmunk primarily occupies coniferous forests in the Southern Rocky Mountains.
