The Permanent Revenue Settlement of Bengal was introduced by Lord Cornwallis. It was implemented in 1793 during the British colonial period in India. The system aimed to provide a stable source of revenue for the British East India Company by fixing the land revenue demand on a permanent basis.

While it aimed to create stability, the Permanent Settlement had long-term negative consequences for the agrarian economy in Bengal.
