- The shortest river in the state of Tamil Nadu, the Thamirabarani starts in Pothigai hills of the Western Ghats in the Ambasamudram taluk.
- It flows through Tirunelveli and Thoothukudi districts and empties at Korkai (Tirunelveli district) into the Gulf of Mannar (Bay of Bengal).
- It was called the Tamraparni River in the pre-classical period, a name it lent to the island of Sri Lanka.
- The old Tamil name of the river is Porunai.
