The Koch dynasty (/kɒ/; 1515–1949) ruled parts of eastern Indian subcontinent in present-day Assam and Bengal. Biswa Singha established power in the erstwhile Kamata Kingdom which had emerged from the decaying Kamarupa Kingdom. The dynasty came to power by overthrowing the Baro-Bhuyans of the region, who had previously ended the brief rule established by Alauddin Hussain Shah.

The dynasty split into three among the descendants of Biswa Singha's three sons: two antagonistic branches Koch Bihar and Koch Hajo and a third branch at Khaspur. Koch Bihar aligned with the Mughals and the Koch Hajo branch broke up into various sub-branches under the Ahom kingdom. Koch Bihar became a princely state during British rule and was absorbed after Indian independence. The third branch at Khaspur (Khaspur kingdom) was absorbed completely into the Kachari kingdom. Raikat is a collateral branch of the Koch dynasty that claim descent from the Sisya Singha, the brother of Biswa Singha.
