Satyanatha Tirtha ; IAST:Śrī Satyanātha Tīrtha), also called Abhinava Vyasaraja, was a Hindu philosopher, scholar, theologian, logician and dialectician belonging to the Dvaita order of Vedanta. He served as the twentieth pontiff of Uttaradi Math from 1660 to 1673. He was a fiery and prolific writer and very ambitious of the glory of Dvaita Vedanta. He is considered to be one of the stalwarts in the history of the Dvaita school of thought, on account of his sound elucidations of the works of Madhvacharya, Jayatirtha and Vyasatirtha. Three of his polemically themed doxographical works are reminiscent of "Vyasatraya". His refutation work Abhinava Gada is a devastating criticism of Appayya's Madhvamathamukhamardhana. His independent treatise Abhinava Chandrika is considered a brilliant work relating to the Brahma Sūtras, being a commentary on Jayatirtha's Tattvaprakashika. His work Abhinava Tarka Tandava refuted the works of rival systems, especially those of Prabhākara of Mimamsa, Ramanuja's Visistadvaita, and Gangesha Upadhyaya, Raghunatha Siromani of the Nyaya school, on the same lines as Vyasatirtha's Tarka Tandava. Indologist B.N.K.Sharma wrote, "His energy and determination to crush out the rivalry of Monism is reflected even in the choice of the titles of some of his works, four of which go by the name "Paraśus" ".

The Uttaradi Math, is one of the main monasteries (matha) founded by Madhvacharya with Padmanabha Tirtha as its head to preserve and propagate Dvaita Vedanta (Tattvavada) outside Tulunadu region. Uttaradi Math is one of the three primary Dvaita monasteries or Mathatraya that descended from Madhvacharya in the lineage of Padmanabha Tirtha through Jayatirtha. After Jayatirtha and Vidyadhiraja Tirtha, Uttaradi Math continued in the lineage of Kavindra Tirtha and later in the lineage of Vidyanidhi Tirtha. The Moola Rama and Moola Sita idols worshipped in the Uttaradi Matha have a long history and are revered among adherents.
