Poliochne, often cited under its modern name Poliochni, was an ancient settlement on the east coast of the island of Lemnos. It was settled in the Late Chalcolithic and earliest Aegean Bronze Age and is believed to be one of the most ancient towns in Europe, preceding Troy I. Anatolian features of the earliest layers were affected by cultural influences from Helladic Greece, about the start of Early Helladic II, ca. 2500 BC.
The site, with houses huddled together sharing party walls, was unearthed by excavations of the Italian School of Archaeology at Athens, beginning in 1930. It is believed that Troy was its main rival commercially; a rivalry that led to the decline of Poliochne circa 2000 BC.
