La Batalla de Argentovaria tuvo lugar en mayo del año 378 entre el Imperio romano y un ejército invasor de lentienses, una tribu de los alamanes, en Argentovaria (cerca de Colmar, Francia). Tras esta derrota, los lentienses desaparecieron de la historia.
El rey de los lentienses, Priarius, murió en la batalla. Graciano, que lideraba el ejército, obtuvo el título de Alemannicus Maximus.

(...) The losses of the Alamans were considerable. The fact that Ammianus provides numbers may go back to his source, possibly a military report; Sabbah 205. The number of casualties among the enemy indicates that this was an important Roman victory and a severe blow to the Alamanni. Iovinus' victory has been compared to that of Julian at Strasbourg in 357; Rosen, 1970: 128; Lorenz, 1997: 82, cf. Drinkwater, 1997, 277-278. Unfortunately, Ammianus does not reveal how large the Alamannic force was, but a comparison with numbers of Alamannic troops presented by Ammianus in the case of two other military Roman-Alamannic encounters may provide some insight. At the battle of Strasbourg in 357 Ammianus reports that the Alamannic army consisted of 35,000 men apart from the various reges and their followers (hos sequebantur potestate proximi reges numero quinque regalesque decem et optimatum series magna armatorumque milia triginta et quinque, 16.12.26); cf. Austin, 1973, 333-335 who thinks that Ammianus is not quite correct and that the number of Alamannic troops was somewhere around 20,000-25,000. After the battle 6,000 Alamannic corpses were lying scattered on the battlefield and an unknown number was carried off by the Rhine (ex Alamannis vero sex milia corporum numerata sunt in campo constrata et alii inaestimabiles mortuorum acervi per undas fluminis ferebantur; 16.12.63). At the battle of Argentaria in 378 the Lentienses, an Alamannic people, are said to have a force of 40,000 men (maioraque conceptantes pagorum omnium incolis in unum collectis cum cuadraginta armorum milibus...sublati in superbiam nostra confidentius irruperunt; 31.10.5); no more than 5,000 survived the battle (ut ex praedicto numero non plus quam quinque milia, ut aestimabatur, evaderent; 31.10.10). Given the numbers of casualties among the Alamanni compared to numbers of troops at the two battles, an educated guess would be that the Alamannic army defeated by Iovinus would have consisted of around 20,000 men.
