Kopperunchinga I (reigned c. 1216–1242 CE) was a Kadava chieftain. He played a major role in the political affairs of Tamil country. Once an official in the service of the Chola king Kulothunga Chola III (1178-1218), Kopperunchinga utilized the opportunity arising out of the Pandyan invasion of the Chola country to become an independent king. Inscriptions of Kopperunchinga I are few since his kingdom was still forming during most of his life, while he was actively engaged in conflict with other powers.
