The Little Navajo River is a tributary of the Navajo River in Archuleta County, Colorado. It joins the Navajo River at Chromo, Colorado. A large portion of its water is diverted, at the Little Oso Diversion Dam, across the Continental Divide to the Rio Grande basin as part of the San Juan–Chama Project.{{Cite web|url=http://www.abcwua.org/San_Juan_Chama_Project.aspx|title=San Juan–Chama Project|website=www.abcwua.org|access-date=2017-06-16}}
