The Lugii (or Legii, Lugi, Lygii, Ligii, Lugiones, Lygians, Ligians, Lugians, or Lougoi) were a large tribal confederation mentioned by Roman authors living in ca. 100 BC–300 AD in Central Europe, north of the Sudetes mountains in the basin of upper Oder and Vistula rivers, covering most of modern south and middle Poland (regions of Silesia, Greater Poland, Mazovia and Little Poland). Their ethnic affiliation is unclear. Most archaeologists identify the Lugians with the Przeworsk culture. They played an important role on the middle part of the Amber Road from Sambia at the Baltic Sea to the provinces of Roman Empire: Pannonia, Noricum and Raetia. A tribe of the same name, usually spelled as Lugi, inhabited the southern part of Sutherland in Scotland.
