Chandragomin (Skt. Candragomin) was an Indian Buddhist lay scholar and poet from the Varendra region of Eastern Bengal. The Tibetan tradition believes challenged Chandrakirti. According to the Nepalese tradition, Chandragomin's student was Ratnakīrti. Chandragomin was a teacher at Nalanda Monastic University during the 5th century. It is unclear when Chandragomin lived, with estimates ranging between 5th to 6th-century CE, but his position at Nalanda signifies he lived during the 5th century.
