Ratnakarashanti (Skt. Ratnākaraśānti; Tib. རིན་ཆེན་འབྱུང་གནས་ཞི་བ་, rinchen jungné shyiwa, Wyl. rin chen 'byung gnas zhi ba, or Skt. Śāntipa; Tib. ཤན་ཏི་པ་, shan+ti pa) (roughly 970 - possibly after 1045) was a famous gatekeeper of the Eastern direction and abbot at the great monastic university of Vikramashila in India who was active in the beginning of the 11th century. He was renowned as the 'Omniscient One of the Degenerate Age' (Skt. kali-kāla-sarvajña). Under the name of Shantipa, he was also one of the eighty-four mahasiddhas, the great realized masters of the Vajrayana teachings.
He was a prolific writer and about forty of his works have been preserved in the Tibetan Tengyur. He wrote extensively both on Sutra and Tantra, which he interpreted consistently according to a particular Nirākāra Yogachara doctrine. Because of this, despite his tremendous importance and influence in India and Tibet, he has been vilified by sectarian Tibetan Madhyamikas, which subsequently diminished has influence in Tibet. He wrote several works on Prajnaparamita and the Hevajra Tantra, and a commentary on the Guhyasamaja Tantra. He wrote two text which contain in their title Madhyamakalamkara, where he argues against Chandrakirti and Shantarakshita.
Taranatha mentions he studied with Naropa. He was a contemporary and a teacher of Atisha and Abhayakaragupta. Other students include Maitripa, Shraddakaravarman (Skt. Śraddhākaravarman) and Drokmi Lotsawa.
There is a famous story that when Ratnakarashanti passed away, Atisha, who was in Tibet at the time, knew that and was grief stricken, saying that now no one in India was able to distinguish anymore between the Buddhist and the non-Buddhist.
