The Aviones or Auiones (*Awioniz meaning "island people") were one of the Nerthus-worshipping Germanic tribes of the 1st century mentioned by Tacitus in Germania, and they lived either in the southern Jutland Peninsula, or on Öland.
[1] Tacitus wrote of the group as defended by rivers and forests: (Original Latin) "Reudigni deinde et Aviones et Anglii et Varini et Eudoses et Suardones et Nuithones fluminibus aut silvis muniuntur.
Nec quicquam notabile in singulis, nisi quod in commune Nerthum, id est Terram matrem, colunt eamque intervenire rebus hominum, invehi populis arbitrantur.
[2](English translation) "There follow in order the Reudignians, and Aviones, and Angles, and Varinians, and Eudoses, and Suardones and Nuithones; all defended by rivers or forests.
Nor in one of these nations does aught remarkable occur, only that they universally join in the worship of Herthum (Nerthus); that is to say, the Mother Earth."
