The Tulu Ashta Mathas of Udupi (Kannada: ಉಡುಪಿಯ ತುಳು ಅಷ್ಟ ಮಠಗಳು) are a group of eight mathas or Hindu monasteries established by Madhvacharya, the preceptor of the Dvaita school of Hindu thought with his direct disciples to be the first Swami, head of the matha.

The ashta mathas are named after the villages in which they were originally located. Today, the mathas are situated in the temple town of Udupi. The mathas work to propagate the Dvaita philosophy. They also administer the famous Udupi Krishna Temple by way of a formal rotation scheme called Paryaya.

When the ashta mathas were formed, Sri Madhvacharya initiated the Swamijis of the mathas in pairs. Each pair of mathas is called Dwandva (literally, two or dual). In the event the current Paryaya Swamiji has difficulty performing his duties, the Swamiji from the Dwandwa matha takes over the responsibility. The four pairs of mathas are: Palimaru and Adamaru; Krishnapura and Puttige; Shirur and Sodhe; and Kaniyooru and Pejavara.Unmarried Tulu speaking Shivalli Madhva Brahmins male's become Swamiji's or Mathadeesha's (pontiffs) of Ashta mutts of Udipi after taking Sanyasa through religious ceremony. They have to remain bachelor or Sanyasi through out their swamiji life.
