Xylophis perroteti, commonly known as Perrotet's mountain snake and the striped narrow-headed snake, is a species of snake in the family Pareidae.

The species, which has no lethal potential as it has a non-venomous bite, is endemic to the Western Ghats of India.

Both the specific name, perroteti, and the common name, Perrotet's mountain snake, are in honor of French naturalist George Samuel Perrottet.

[3] X. perroteti is found in the Western Ghats in the Indian states of Kerala and Tamil Nadu.

[1] The natural habitat of X. perroteti is forest at altitudes of 1,500–2,380 m (4,920–7,810 ft).
