The Bannuchi (Pashto: بنوڅي), also Banutsi, Banusi or Banisi, are a Pashtun tribe inhabiting the Bannu District of the Khyber Pakhtunkhwa province of Pakistan and North Waziristan of the Federally Administered Tribal Areas, with some members settled in Afghanistan.
The Bannnuchis originally lived in the Shawal area, which lies partly in the present-day North Waziristan tribal agency of Pakistan and partly in the Paktika Province of Afghanistan. The Bannuchi, as well as their cousin tribe the Dawars descend from the Shitak supertribe who were settled in Shawal. In the 14th century, the Wazir tribe of the Afghans, who were living in Birmal in the west, migrated eastwards to the Shawal area and fell into dispute with the Shitaks (Bannuchis and Dawars), and succeeded to oust the Shitaks northeastwards towards the land between the Tochi and Kurram rivers. Eventually, the Bannuchi Shitaks migrated to the Bannu District, where the Afghan tribes of the Mangal and the Honai, as well as the Khattak were already settled. The Bannuchis first defeated and drove away the Mangals and the Honais, then gradually pushed the Khattaks northwards to Kohat and Karak, and eventually captured and settled in Bannu District.
