The Teutons or Teutones are mentioned as a Germanic tribe by Greek and Roman authors, notably Strabo and Marcus Velleius Paterculus and normally in close connection with the Cimbri, whose ethnicity is contested between Gauls and Germani.

According to Ptolemy's map, they lived in Jutland, in agreement with Pomponius Mela, who placed them in Scandinavia (Codanonia).
