Janamejaya (Sanskrit: जनमेजय) was a Kuru king who reigned during the Middle Vedic period (12th or 11th century BCE). Along with his predecessor Parikshit, he played a decisive role in the consolidation of the Kuru state, the arrangement of Vedic hymns into collections, and the development of the orthodox srauta ritual, transforming the Kuru realm into the dominant political and cultural center of northern Iron Age India.
