Athanaric or Atanaric was king of several branches of the Thervingian Goths for at least two decades in the 4th century. Throughout his reign, Athanaric was faced with invasions by the Roman Empire, the Huns and a civil war with Christian rebels. He is considered the first king of the Visigoths, who later settled in Iberia, where they founded the Visigothic Kingdom.

The Thervingi, Tervingi, or Teruingi 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.
