The Auscii or Ausci were an Aquitani tribe dwelling around present-day Auch during the Iron Age.
Alongside the Tarbelli, they were one of the most powerful peoples of Aquitania.
[1] They are mentioned as Ausci by Caesar (mid-1st c. BC), Pliny (1st c. AD) and Pomponius Mela (mid-1st c. AD),[2][3][4] and as Au̓skíois (Αὐσκίοις) by Strabo (early 1st c.
[5][6] The ethnonym Auscii may be related to the prefix eusk-, meaning 'Basque' in the Basque language (euskara).
[7] The city of Auch, attested as civitas Auscius in the early 4th century AD, is named after the tribe.
