The Μetsovitikos (Greek: Μeτσοβίτικος) river is one of the primary tributaries of the Arachthos in Epirus, Greece.

A longitudinal, narrow gorge is formed within a closed circle of mountains.

In the location Tria Chania the flow of the Metsovitikos river turns south and enters a second, much wider valley which it crosses along the slope of mountain Peristeri (or Lakmos) down to the area of Baltouma.

At this point it merges with the aquatic arm formed by the confluence of rivers Vardas and Zagoritikos which spring in the Eastern and Central Zagori respectively, constituting the second primary bed of the river Arachthos.

The valley of the Metsovitikos river was the main passage between Epirus, on one hand, and Macedonia and Thessaly, on the other.
