Tamil Jains (Tamil Samaṇar, from Prakrit samaṇa "wandering renunciate") are ethnic-Tamils from the Indian state of Tamil Nadu, who practice Jainism, chiefly the Digambara school (Tamil ). The Tamil Jain is a microcommunity of around 85,000 (around 0.13% of the population of Tamil Nadu), including both Tamil Jains and north Indian Jains settled in Tamil Nadu. They are predominantly scattered in northern Tamil Nadu, largely in the districts of Tiruvannamalai, Kanchipuram, Vellore, Villupuram, Ranipet and Kallakurichi. Early Tamil-Brahmi inscriptions in Tamil Nadu date to the third century BCE and describe the livelihoods of Tamil Jains. Samaṇar wrote much Tamil literature, including the important Sangam literature, such as the Nālaṭiyār, the Silappatikaram, the Valayapathi and the Seevaka Sinthamaṇi. Three of the five great epics of Tamil literature are attributed to Jains. Some scholars believe that Jain philosophy must have entered South India some time in the sixth century BCE. Literary sources and inscription state that Bhadrabahu came over to Shravanabelagola with a 12,000-strong retinue of Jain sages when north India found it hard to negotiate with the 12-year long famine in the reign of Chandragupta Maurya. Even Chandragupta accompanied this constellation of sages. On reaching Shravanabelagola, Bhadrabahu felt his end approaching and decided to stay back along with Chandragupta and he instructed the Jain saints to tour over the Chola- and Pandyan-ruled domains. According to other scholars, Jainism must have existed in South India well before the visit of Bhadrabhu and Chandragupta. There are plenty of caves as old as fourth century with Jain inscriptions and Jain deities found around Madurai, Tiruchirāppaḷḷi, Kanyakumari and Thanjavur. A number of Tamil-Brahmi inscriptions have been found in Tamil Nadu that date from the second century BCE. They are regarded as associated with Jain monks and lay devotees. The exact origins of Jainism in Tamil Nadu is unclear. However, Jains flourished in Tamil Nadu at least as early as the Sangam period.
