A matha (/mʌt/; Sanskrit: मठ, maṭha), also written as math, muth, mutth, mutt, or mut, is a Sanskrit word that means 'institute or college', and it also refers to a monastery in Hinduism. An alternative term for such a monastery is adheenam (also transliterated ādīnam, adinam, aadheenam, aadheenm, etc.). The earliest epigraphical evidence for mathas related to Hindu-temples comes from the 7th to 10th century CE.
The most famous Advaita Vedanta mathas or peethams, which came to be affiliated with the Advaita tradition in the 14th century, are Govardhanmaṭha Pīṭhaṃ at Puri, Odisha; Śārada Pīṭhaṃ at Sringeri, Karnataka; Kalika Pīṭhaṃ at Dvāraka, Gujarat; Jyotirmaṭha Pīṭhaṃ at Badari, Uttarakhand; and Sri Kanchi Kamakoti Peetham at Kanchi, Tamil Nadu.
