Tamil Nadu occupies the southeastern tip of the Indian peninsula, bordered by the Bay of Bengal to the east, the Indian Ocean to the south, Kerala to the west, Karnataka to the northwest, and Andhra Pradesh to the north. The state features diverse terrain — from the coastal plains of Coromandel to the Western and Eastern Ghats mountain ranges, the fertile Cauvery delta, and the arid regions of the south. Major rivers include the Cauvery, Vaigai, Palar, and Tamiraparani. The state enjoys a tropical climate with distinct monsoon seasons, making it agriculturally productive while also supporting year-round business operations. The 1,076-kilometre coastline hosts several major ports that facilitate international trade.
Tamil Nadu boasts India's second-largest state economy with key sectors including automobile manufacturing (often called the Detroit of Asia), information technology and IT-enabled services, textiles, leather, heavy engineering, chemicals, and agriculture. Chennai serves as a major IT and automotive hub, while Coimbatore leads in pump manufacturing and textile production. The state contributes significantly to India's automotive exports and is home to major SEZs and industrial corridors. The MSME sector alone employs millions, and the startup ecosystem continues to grow rapidly, particularly in fintech, healthtech, and edtech sectors.
