The Adyar River, originating from the Chembarambakkam Lake in Chengalpattu district, is one of the two rivers which winds through Chennai, South India, and joins the Bay of Bengal at the Adyar Estuary. The 42 km long river contributes to the estuarine ecosystem of Chennai. Despite the high pollution levels, boating and fishing take place in this river. The river takes in surplus water from about 40 tanks and lakes, small streams and the rainwater drains in the city. Most of the waste from the city is drained into this river and the Cooum.

Adyar Estuary and Creek and the Theososphical Society on the Estuary's southern side has been a haven for migratory and resident birds for years. Although the number has been in decline due to pollution and anthropogenic activities, they still attract hundreds of birds. Even before few years the Theosophical Society has come out with a CD on 'Birds of Adyar', compiled by Trust for Environment Monitoring and Action Initiating. The proposed 'Adyar Poonga' may be a first towards restoring this fragile but vibrant eco-system.

The Theosophical Society, Anna University, Madras Boat Club, the Brodie Castle , Tamil Nadu College of Music are prominent institutions located in the banks of Adyar. Adyar Estuary is now a protected wildlife reserve.
