The names of the principal Afšār clans are: Alplū, Arašlū, Bekešlū, Gündüzlü, Imirlü, Köse Aḥmedlū, Pāpālū, Qāsemlū, Qereḵlū and Qirqlū. The Imirlū clan is probably related to the Imir tribe, one of the original Ḡuz tribes. Branches of the Aynallū (variants: Inānlū, Imānlū), Uṣālū (variant: Uṣānlū) and Ustāǰlū tribes were also incorporated into the Afšār tribe.
