The southern Rocky Mountain wolf (Canis lupus youngi) is a possibly extinct subspecies of gray wolf found over southeastern Idaho, southwestern Wyoming, northeastern Nevada, Utah, western and central Colorado, northwestern Arizona and northwestern New Mexico. It is a light-colored, medium-sized subspecies closely resembling C. l. nubilus, though larger, with more blackish-buff hairs on the back.^[2]

As of 2005,^[3] it is considered a valid subspecies by MSW3, though it is classed as a synonym of C. l. nubilus by the United States Fish and Wildlife Service.^[4]

Wolves have reestablished in Idaho and Wyoming, however, Canis lupus youngi is probably extinct, as the wolves there, as of 2015, are of subspecies Canis lupus occidentalis.
