Banū or Bannu is a city located in Bannu District in southern Khyber Pakhtunkhwa, Pakistan. Founded by Sir Herbert Benjamin Edwardes in 1848 during the British colonial era, Bannu was once a British military base used for action against the Pashtun border tribes of the Tochi Valley and Waziristan. Bannu's residents are primarily members of the Banuchi tribe and speak a dialect of Pashto that is similar to the distinct Wazir dialect.
The major industries of Bannu are cloth weaving, sugar mills and the manufacturing of cotton fabrics, machinery and equipment. It is famous for its weekly Jumma fair. The district forms a basin drained by the Kurram and Gambila rivers, which originate in the hills of Waziristan. Although Bannu is surrounded by rugged and dry mountains, it is a fertile place, and early English visitors had been known to refer to it as a "paradise" – see the beautiful description by Edwardes quoted by Thornton. The city of Bannu is the only urban area of any kind throughout the entire district of Bannu.
