Chudamani Vihara was a Buddhist vihara (monastery) in Nagapattinam, Tamil Nadu, India. Chudamani Vihara was constructed in 1006 CE by the Srivijayan king Sri Vijaya Maravijayattungavarman with the patronage of Rajaraja Chola. The vihara building survived in dilapidated condition till 1867, when Jesuit missionaries demolished it. Since 1856, about 350 Buddha bronzes have been found at Nagapattinam, dating from the 11th to the 16th century.
