Biswanath district

Biswanath district () is an administrative district in the state of Assam in India. It is one of the newly created districts in 2015, declared by Assam Chief Minister Tarun Gogoi on 15 August 2015.

The district is created amalgamating Gohpur and most part of Biswanath Sub division on earlier Sonitpur district. The district is bounded by Arunachal Pradesh on north, Golaghat, Brahmaputra River on the south, Lakhimpur district on the east and Sonitpur district on the west. The administrative headquarter is located at Biswanath Chariali.

On 31 December 2022, the district remerged with existing Sonitpur district ahead of delimitation process by ECI in the state.

However, on August 25, 2023, the Assam cabinet announced the restoration of Biswanath's district status.
