Palar (Tamil: பாலாறு நதி), (Kannada: ಪಾಲಾರ್ ನದಿ), (Telugu: పాలార్ నది) is a river of southern India. It rises in Nandi Hills, India in Kolar district of Karnataka state, and flows 93 kilometres (58 mi) in Karnataka, 33 kilometres (21 mi) in Andhra Pradesh and 222 kilometres (138 mi) in Tamil Nadu before its confluence into the Bay of Bengal at Vayalur about 100 kilometres (62 mi) south of Chennai. It flows as an underground river for a long distance only to emerge near Bethamangala town, from where, gathering water and speed, it flows eastward down the Deccan Plateau. The cities of Ramanaickenpet, Vaniyambadi, Ambur, Gudiyatham, Vellore, Melvisharam, Arcot, Walajapet (Anaicut), Kanchipuram, and Chengalpattu are located on banks of Palar River. Of all the total of seven tributaries, the chief tributary is Cheyyar River.
Palar river water from Palar anicut is diverted to the Poondi reservoir located in Kosasthalaiyar River basin and to Chembarambakkam Lake located in Adayar River basin. These two reservoirs are major water supply points to Chennai city. After commissioning of the Telugu Ganga project to supply nearly 1000 million litres per day of Krishna River water to the Chennai city, the dependence on Palar river water has reduced drastically.
