Chandragomi (c 7th century)  famous grammarian. According to Tibetan sources, he was born in a ksatriya family in the northern varendra region. He subsequently embraced buddhism.

Chandragomi was a disciple of Sthiramati, the abbot of Nalanda Mahavihar. At Nalanda Chandragomi studied Buddhism, sanskrit grammar, literature, logic. It is widely believed that Chandrakirti, the chancellor of Nalanda Mahavihar, received him cordially after his return from a tour of South India and Sri Lanka. Later on, Chandragomi became the abbot of Nalanda.

Chandragomi wrote about 36 books on the Buddhist vajrayana worship and several treatises on tara and Manjusri. However, it is not clear whether Chandragomi, the grammarian and Nyaya philosopher, and the tantric Chandragomi are the same. Bhartrihari in Vakyapadiya and Kalhan in Rajatarangini mention Chandracharya, a grammarian. Some believe that Chandracharya and Chandragomi are the same. Vamanajayaditya, in his annotation Kashika, cites 35 rules from Chandragomi. Therefore, it is believed that Chandragomi was alive in the 7th century or earlier.

Chandragomi's famous grammar, chandravyakaran (Grammar by Chandra), a simplification on Panini's Astadhyayi, was in wide circulation in Sri Lanka, Kashmir, Tibet and Nepal. It is believed that Chandragomi also wrote a book on logic named Nyayasiddhyaloka. [Kanailal Ray]
