The Tulingi were a small tribe closely allied to the Celtic Helvetii in the time of Julius Caesar's conquest of Gaul.
At the Battle of Bibracte in 58 BCE, they were, with the Boii and a few other smaller tribes, allies of the Helvetii against the Roman legions of Caesar.
The only reference is Caesar, who relates that with the Helvetii and the others they burned their homes and became part of the column of migrants seeking a new country in southern France.
This was championed by Rudolf Much and other authors who proposed the now-discredited theory of "Alpine Germanic" tribes in the late Iron Age, to whom the Tulingi were counted.
About 360 AD Rufus Festus Avienus in Ora Maritima mentions a number of peoples living on the upper Rhône in Valais.
