Udayin (reigned -444 BCE or 373-357 BCE) also known as Udayabhadra was a king of Magadha in ancient India. According to the Buddhist and Jain accounts, he was the son and successor of the Haryanka king Ajatashatru. Udayin laid the foundation of the city of Pataliputra at the confluence of two rivers, the Son and the Ganges. He shifted his capital from Rajagriha to Pataliputra due to the latter's central location in the empire.
