Chennai (Tamil: சென்னை), formerly Madras (மெட்ராஸ் Meḍrās), is the largest coastal city in southern India and the capital of the state of Tamil Nadu. It is on the east coast of peninsular India. Though Chennai traces its history to Fort St George and the adjoining village of Madrasapattinam founded by the British East India Company in 1640, some residential districts of the city are older. With a metropolitan population of over 11 million (2025), Chennai is the fifth-largest city in India, and the second-largest in southern India after Bengaluru.
