The archaeological site at Vlochos (Greek: Βλοχός [vlo̞χˈo̞s̠]) is located at the northeast corner of the western Thessalian plain, in the regional unit of Karditsa, Greece. The site is centred around the large hill of Strongilovouni (Greek: Στρογγυλοβούνι) south of the modern village, and contains the remains of several urban settlements of Classical Antiquity. The remains cannot be securely identified with any city known from ancient sources, but the size of the settlement indicates that it must have been one of the poleis or city-states of the region.
