Chennai District, formerly known as Madras district,Template:Efn is one of the 38 districts in the state of Tamil Nadu, India. It is the smallest and the most densely populated district in the state. The district is almost coterminous with the city of Chennai, which is administered by the Greater Chennai Corporation, except for Madipakkam-B / Madipakkam-II revenue village which is administered by Kovilambakkam rural village panchayat as Kovilabakkam panchayat wards 3,4 and 5 but is under Zone-14 (Puzhuthivakkam) of Greater Chennai Corporation for Disaster and Revenue Management purpose.[1] It is surrounded by Tiruvallur district in the north and the west, Kanchipuram district in the south-west, Chenglpattu district in the south, and the Bay of Bengal in the east.

The district consists of two civic bodies, the megacity of Chennai and Kovilabakkam rural village panchayat wards 3, 4 and 5 (Madipakkam-B / Madipakkam-II revenue village colloquially known as Sunnambu Kolathur),[1] which forms the core and the most notable portion of the much bigger Chennai metropolis, or officially, the Chennai Metropolitan Area.

It is situated on the northeastern corner of Tamil Nadu along the Coramandel coast, a region bounded by the Bay of Bengal and is surrounded inland by the districts of Tiruvallur, Kanchipuram and Chengalpattu. It lies between 12°59' and 13°9' of the northern latitude and 80°12' and 80°19' of the eastern longitude at an average altitude of 6 metres above sea level on a 'sandy shelving breaker swept' beach.
