In Hindu mythology, Keshin (Sanskrit: केशिन्, lit. 'the hairy one/long-haired' IAST: Keśin), also called Keshi (Sanskrit: केशी IAST: Keśī) is a horse-demon, killed by Krishna, an Avatara of Vishnu. The demon was dispatched by Krishna's evil uncle Kamsa, who was destined to die at Krishna's hands.
The tale of the slaying of Keshi is told in the Hindu scriptures of Bhagavata Purana, Vishnu Purana and Harivamsa. Krishna is often praised as Keshava - the slayer of Keshi - in scriptures.
