The Lentienses (German Lentienser) were a 4th-century Germanic tribe associated with the Alemanni, in the region between the river Danube in the North, the river Iller in the East, and Lake Constance in the South, in what is now southern Germany.
There are only two mentions of the Lentienses, both by the Roman historian Ammianus Marcellinus (330–395).
[1] Secondly, they were mentioned when they crossed the frozen Rhine in February 378, invading the Roman Empire.
They were defeated by the Roman emperor Gratianus in the Battle of Argentovaria (modern Colmar in Alsace), when their king, Priarius, died.
The Latin name "Lentienes" was formed from the name of the Celtic village Lentia; today a region north of Lake Constance is called Linzgau.
