Tsivlos (Greek: Τσιβλός) is a small mountain village in the municipality of Akrata, Achaea, Greece.

It is built on the slopes of Mount Chelmos (Aroania), above the river Krathis, at about 750 m elevation.

Tsivlos was mentioned as the settlement of Civlò in the census of the Venetian Francesco Grimani in 1700; it had 33 families and 148 inhabitants.

On Sunday March 24, 1913, a large volume of rocks and soil fell from the nearby mountain of Gerakari which devastated the village of Sylivaina and fell into the Krathis river.

The river water flooded a large part of Tsivlos, creating a lake with a depth of 80 m and an area of around 200 hectares.
