Odantapuri was a prominent Buddhist Mahavihara in what is now Bihar Sharif in Bihar, India. It is believed to have been established by the Pala ruler Gopala I in the 8th century. It is considered the second oldest of India's Mahaviharas after Nalanda and was situated in Magadha. Inscriptional evidence also indicates that the Mahavihara was supported by local Buddhist kings like the Pithipatis of Bodh Gaya.
