Esgairgeiliog (also known as Ceinws) is a village in Powys (formerly Montgomeryshire), Wales, UK.
It is situated at the junction of the Afon Glesyrch's and Afon Dulas' valleys.

Behind the village is the former Era slate quarry, in the Glesyrch valley, and the Centre for Alternative Technology lies about a mile south of the village.

The minor road on the east side of the Afon Dulas is believed to be of Roman origin.
In 1910, this road was still mostly cobbled, with sections that crossed bedrock showing deep wheel ruts.

Immediately after the Second World War, the Forestry Commission established the Dovey Forest (later known as the Dyfi Forest) in the land between Corris and Aberangell.
A major camp was established on the east side of Esgairgeiliog.
