368–377) was a Roman army officer in late antiquity who served under the emperors Valentinian I and Valens.
Lupicinus was serving as the commander of Roman troops in the diocese of Thrace (comes rei militaris per Thracias) in c. 377 during the events which resulted in the Gothic War.
There he oversaw the settlement of the Goths within the empire along the Lower Danube, after which, he and the dux Maximus foolishly proceeded to extort and starve them.
Famished and humiliated, the Goths broke into an open revolt that led to the Gothic War of 376 and the catastrophic Battle of Adrianople in which the emperor Valens was killed.
After orchestrating a failed assassination attempt of the Gothic leaders while ostensibly meeting with them to discuss a peace, Lupicinus led his troops into a total defeat at the Battle of Marcianople.
