Sri Vadiraja Tirtha (Tulu: ಶ್ರೀ ವಾದಿರಾಜ ತೀರ್ಥರು), traditionally 1480–1600, a Haridasa, was a Shivalli Tulu Brahmin and native of the village of Hoovinakere, near Kumbhashi in Kundapura taluk, Udupi District in Karnataka state. His parents were Ramacharya and Gauri. He is considered amongst the highest saints in the Madhva hierarchy, next only to Srimad Ananda Tîrtha and Sri Jayateertha. He also studied under Vyasarayaru. He is regarded as an incarnation of Latavya and hence popularly known as "BHAVISAMEERA" which means he will come to Vayu Devara Padavi or title in future. He was not only a great poet but also very effective in the administration of the Udupi Matha system. He brought about many changes to the operational system of the Matha which by itself showed his high placing in the Madhva hierarchy.
He became a Sanyasi at the young age of 8. The pre-sanyasa name given to Sri Vadiraja was Bhuvaraha. He worshipped Lord Vishnu in the form of Hayagriva.
It was Sri Vadirajateertha who changed the Paryaya system of Udupi to two years from the earlier practice of 2 months. This extension of each individual Paryaya enabled the Swamis to travel far and wide and spread the message of Madhva tradition. Another of Sri Vadirajateertha's achievements is that he lived a life of 120 year and performed Lord Krishna's Paryaya at Udupi 5 times. He is the first Sanyasi who entered the Vrindavana (his own TOMB) alive after worshipping that for nearly 3 years. The only other saint to have followed similar way of leaving this materialistic world is Sri Raghavendra Swamy of Mantralaya.
