The Qazi family of Lakhnauti was a medieval Bengali Muslim family who lived in the royal city of Lakhnauti in the Bengal Sultanate. The family was founded by Taj ad-Din an-Nahwi in the 15th century, and has produced numerous influential judges and scholars. The descendants of Shah Manjhan later moved to Gujarat and neighbouring states.
The historic city of Lakhnauti, now in present-day Nawabganj, Bangladesh, was the royal capital of the Sultanate of Bengal and experienced an influx of scholars during this period.
