- S. a. willkonskii: Large and heavily marked
- North-eastern Turkey, Caucasus and north-western Iran to Turkmenistan
- S. a. sanctinicolai: smaller
- S. a. harmsi:
- S. a. biddulphi:
- S. a. ma:
- S. a. yamadae:
- Mountains of southern Taiwan
Himalayan Owl was formerly considered a subspecies of this species.
