Chilarai (real name Sukladhwaja; 1510–1571 AD) was the 3rd son of Biswa Singha, founder of the Koch Dynasty in the Kamata Kingdom and younger brother of Nara Narayan, the 2nd king of the Koch dynasty of the Kamata kingdom in the 16th century.

[3] It was only due to his royal patronage that Sankardeva was able to establish the ekasarana-namadharma in Assam and bring about his cultural renaissance.

Several rulers, namely the then king of Manipur and the Khasi tribal chief (Viryyavanta), submitted to Chilaray.

Chilaray is said to have never committed brutalities on unarmed common people, and even those kings who surrendered were treated with respect.

He was harsh to kings and soldiers who refused to surrender, but neither him nor his brother ever annexed territories or oppressed the common people.
