Lake Mornos is an artificial reservoir in central Greece identified at latitude 38.53205 and longitude 22.14706. It is formed by the Mornos River and functions as a water supply source for regions of Greece.

As a well-known regional reservoir, the lake and its dam attract visitors interested in engineering structures and landscape views along the reservoir shoreline. Roads and viewpoints near the dam provide vantage points for observing the water body and surrounding mountains.
