Somadeva Suri was a south Indian Jain monk of the 10th century CE (fl. 959-66, possibly born in Bengal about 920), author of a work known as Upasakadyayana "chapter on lay followers (upasakas)", a central work of Digambarashravakacara literature, i.e. instructions and prescriptions for shravakas or Jain followers.
Somadeva Suri also wrote the Nitivakyamrtam " Nectar of the Science of Polity" (ed. Sundaralala Sastri 1976, Menta 1987), a treatise on statecraft. The text of the Nitivakyamrtam mentions that Somadeva was also the author of a literary work called Yashastilaka (see Kavyamala, 70)
