Thiruvottriyur Subdistrict (Thiruvotriyur or TVT) is an effective suburb in North Chennai administered by the Chennai Corporation, but remains part of Tiruvallur district. It is administrated as a taluk or subdistrict, located to the north of Chennai. Due to its proximity to Parrys and Chennai Central along with comparatively cheaper residential space and decent amenities, it is fast becoming a sought after residential destination. Tiruvottriyur which is one of the oldest habitations by the sea, has a diverse residential population due to the industrial units, trading activity and nearby fishing hamlets. The area is easily accessible by Metropolitan Transport Corporation (MTC) buses from across the city and has a bus terminus. The area is also served by Tiruvottiyur railway station of the Chennai Suburban Railway Network. As of 2011, the subdistrict (taluk) had a population of 249,446, and there is also an eponymous revenue village within the taluk.
