The Cumbarjua Canal is a distributary channel formed by the merger of the Mandovi and Zuari rivers in Goa, India. Its flow has led to the formation of river deltas; the most prominent of them are Ilhas de Goa, Cumbarjua and St Estevam.

The shallow mangroves of the waterbody is the natural habitat of the Indian Mugger crocodile as well as exotic birds and flying fish. Wildlife boating tours are now a common tourist activity.

Banastarim Wetlands

The Banastarim Wetlands, a large swamp and biosphere reserve on the Ilhas de Goa, is fed by the Cumbarjua Canal.
