The Travancore vine snake (Ahaetulla travancorica), is a species of tree snake endemic to the southern Western Ghats of India.
It was formerly considered conspecific with A. dispar (which is now considered to have a more northerly distribution in the Western Ghats), but a 2020 study found it to represent a new species.
This species is endemic to the Agasthyamalai Hills of the southern Western Ghats in Tamil Nadu and Kerala. The specimen that the species was described from originates from a single locality in Peppara Wildlife Sanctuary. The Shencottah Gap north of the Agasthyamalais separates it from its closest relative, A. dispar.
This species is found in high-elevation shola forests in the Western Ghats above 1000 msl.
