The Nilgiri gracile skink (Subdoluseps nilgiriensis) is a species of skink found in Western Ghats ranges in the Nilgiri hills in Tamil Nadu, South India.

This species was named after its type locality - the Nilgiri hills, in the Western Ghats of South India.

Subdoluseps nilgiriensis was discovered by scientists in the Anaikatti and Mulli hills of the Nilgiri district of Tamil Nadu, in a farmland surrounded by deciduous forests.

Subdoluseps nilgiriensis is most likely a diurnal, insectivorous, skink that lives on dry leaf-litter in deciduous forest belts in mid-elevations (800 m) of these hills.

These skinks were seen in marginally human-occupied areas as well, including the place where from they were first sighted.
