Achakzai (Pashto: اڅکزی), pronounced a.t͡sak.zai in Pashto, is a Pashtun tribe that resides on both sides of current Pakistan Afghanistan border, centered on Killa Abdullah District with some clans as far away as Afghanistan’s Kandahar Province.
The Achakzai are a Pashtun tribe, a section of the larger Zirak Durrani tribe. Their name comes from the fact that they trace agnatic (patrilineal) descent from Achak Khan - the paternal grandson of Barak Khan, from whom are descended the Barakzai tribe of Pashtuns; thus, the Achakzai are a branch or sept of the Barakzai, who are themselves a branch of the Zirak Durrani tribe.
They are divided into two sub-tribes, namely:
- Gujanzai (whose branches are Hameedzai, khawajazai, Ashezai, Nusratzai, Malezai, Usmanzai) (Masazai)
- Badinzai (whose branches are Yonus, Ghabizai, Kakozai, Shamshozai, Panizai, Piralizai Shabozai, (Badizai)
