The Southern Rocky Mountain wolf (Canis lupus youngi) is an extinct subspecies of gray wolf which was once distributed over southeastern Idaho, southwestern Wyoming, northeastern Nevada, Utah, western and central Colorado, northwestern Arizona, and northwestern New Mexico.

Habitat:

Breeding:

Unknown.
