Gallic tribe
The Ceutrones (or Centrones) were a Gallic tribe dwelling in the Tarantaise Valley, in modern Savoie, during the Iron Age and Roman period.
Name.
They are mentioned as "Ceutrones" by Caesar (mid-1st c. BC), "Keútrōnes" (Κεύτρωνες; Κέντ-) by Strabo (early 1st c. AD), "Ceutrones" by Pliny (1st c. AD), and as "Keutrónōn" (Κευτρόνων) by Ptolemy (2nd c. AD).
The hamlet of Centron, located in the village of Montgirod, may be named after the Gallic tribe.
They had a homonym tribe in Gallia Belgica, documented in 54 BC, which was probably a "pagus" of the Nervii.
Geography.
The Ceutrones dwelled in the Tarantaise Valley, along the upper Isère river, near the Little St Bernard Pass (Alpis Graia) on the route stretching from the Rhône Valley to the north of the Italian Peninsula. Their territory was located north of the Graioceli and Medulli, southeast of the Allobroges, southwest of the Veragri, and west of the Salassi, on the other side of the Alps.
 ;templatestyles src="Template:Blockquote/styles.css" / ;Among the passes which lead over from Italy to the outer—or northerly—Celtica, is the one that leads through the country of the Salassi, to Lugdunum; it is a double pass, one branch, that through the Ceutrones, being practicable for wagons through the greater part of its length, while the other, that through the Poeninus, is steep and narrow, but a short cut.
Their chief town was known as Axima (modern Aime-la-Plagne). Renamed to Forum Claudii Ceutronum under Claudius (41–54 AD), probably when the Ceutrones were granted Latin Rights, it became the chief town of Alpes Graiae, one of the two divisions of the province of Alpes Graiae et Poeninae. The procurator of the province had an occasional residence in the Ceutronian chief town. In Late Antiquity, the city lost its position to Darentasia (Moûtiers), which became the capital of the Diocese of Tarentaise in 426.
History.
In the mid-1st century BC, the Ceutrones are mentioned by Julius Caesar as a tribe hostile to Rome. In what appears to be a concerted attack, they attempted to prevent his passage through the upper Durance along with the Caturiges and Graioceli in 58 BC.
 ;templatestyles src="Template:Blockquote/styles.css" / ;There [Titus Labienus] enrolled two legions, and brought out of winter quarters three that were wintering about Aquileia; and with these five legions made speed to march by the shortest route to Further Gaul, over the Alps. In that region the Ceutrones, the Graioceli, and the Caturiges, seizing points on the higher ground, essayed to stop the march of his army. They were repulsed in several actions; and on the seventh day he moved from Ocelum, the last station of Hither Gaul, into the borders of the Vocontii in Further Gaul.
Culture.
The Ceutrones were possibly of Celto-Ligurian origin.
Economy.
The Ceutrones were known for copper mining. They also produced a renowned cheese named "vatusicus".
