The Melingoi or Milingoi (Greek: Μηλιγγοί) were a Slavic tribe that settled in the Peloponnese in southern Greece during the Middle Ages. In the early decades of the 7th century, Slavic tribes (Sclaveni) settled throughout the Balkans following the collapse of the Byzantine Empire's defense of the Danube frontier with some groups reaching as far south as the Peloponnese. The Sclaveni often settled in small groups (i.e., families and clans) and their demographic impact in mainland Greece was both weak and diffuse. Of these, two groups are known by name from later sources, the Melingoi and the Ezeritai, of whom the Melingoi settled on the western slopes of Mount Taygetos. The origin and etymology of the name Melingoi is unknown.
