The Kewat, also spelled Kevat, is an ethnic group and Hindu caste, found in the states of Assam, Bihar, Tripura, Uttar Pradesh and West Bengal in India. They are the traditional boatmen of northern India, and also in neighbouring country Nepal. They natively speak the Kewat language, an Eastern Indo-Aryan language. But the language is now declining as they have begun to speak the languages commonly used in the regions where they live.
