The Thervingi, Tervingi, or Teruingi (sometimes pluralised Tervings or Thervings) were a Gothic people of the plains north of the Lower Danube and west of the Dniester River in the 3rd and the 4th centuries. They had close contacts with the Greuthungi, another Gothic people from east of the Dniester, as well as the Roman Empire. They were one of the main components of the large movement of Goths and other peoples over the Danube in 376, and they are seen as one of the most important ancestral groups of the Visigoths.
