Acharya Manatunga (c. seventh century CE) was the author of the Jain prayer Bhaktamara Stotra.

[2][3] According to a Digambar legend, Manatunga composed the Bhaktamara Stotra when he was locked up in prison for failing to appear before the royal court of King Bhoja.

The oldest mention of the legend of the composition of the Bhaktāmara Stotra is in Acharya Prabhachandrasuri's Prabhavakacarita written in 1277 AD.

The second oldest mention of Manatungsuri is again a piece of Śvetāmbara literature, the 1305 text Prabandha-Chintamani authored by Merutungasuri.

[3] Earliest mentions of Acharya Manatungsuri in Digambara literature can only be dated to 1665 AD in Bhaktamar Charit by Bhattaraka Vishwabhushan.
