Ratnagupta was a Buddhist temple in Pravarapura, modern-day Shrinigar. It may also have been named Ratnaraśmi, apparently after a Paṇḍita Ratnaraśmi who built the temple. It was a center of activity of Tibetan translators for many decades in the eleventh century, including Ngok Lotsāwa Loden Sherab and Patsab Lotsāwa Nyima Drak.
