The Silings or Silingi (Latin: Silingae, Ancient Greek Σιλίγγαι – Silingai) were a Germanic tribe, part of the larger Vandal group. The Silingi at one point lived in Silesia, and the names Silesia and Silingi may be related.
The Silingi are first mentioned by Claudius Ptolemaeus in the 2nd century, who wrote that they had lived south of the Suevic Semnone tribe and north of the Carpathian Mountains, around what now is Silesia:
Back below the Semnones the Silingae have their seat, [...]; and below the Silingae the Calucones and the Camavi up to Mt. Melibocus, from whom to the east near the Albis river and above them, below Mt. Asciburgius, the Corconti and the Lugi Buri up to the head of the Vistula river.
The tribe of Nahanarvali is speculated by modern scholars to be the same people as the Silingi. Tacitus Germania, 43 mentions the Naharvali as the keepers of sanctuary of the Lugian federation (the grove to twin gods Alcis). Tacitus does not mention the Silingi; however, he places the Naharvali in about the same geographical area in which Ptolemaeus placed the Silingi.
During the reign of the Roman Emperor Marcus Aurelius, (A.D. 161–180) the Silingi lived in the "Vandal mountains", later part of the former Sudetenland, which now is part of the Czech Republic.
