Cynus (Ancient Greek: Κύνος, Kúnos) is an ancient settlement site with finds of the Bronze and Early Iron Age, which was discovered on the edge of the town of Livanates in Central Greece. The archaeological site is thus also referred to as Pyrgos Livanaton. The coastal site, overlooking the Euripos and neighbouring Euboea, has been identified with the city of Kynos, mentioned in the Homeric catalogue of ships (Il. II 531–533.) Kynos was the seaport of Opus in Eastern Locris.
The site was excavated between 1985 and 1995 by the 14th Ephorate of Prehistoric and Classical Antiquities in Lamia. The findings of these excavations have so far only been made known in preliminary reports.
Kynos, like nearby Mitrou, Kalapodi, Elateia, and Lefkandi, shows continuous occupation throughout the transition from the Mycenaean palatial period to the Early Iron Age.
