Flavius Jovinus (c. 310 - 370 AD) was a Roman general and consul of the Western Roman Empire. He was of Gallic or Germanic origin and was both born and buried in Durocortorum, modern day Reims.^[1]

Jovinus spent his military career in Gaul, first appearing in the historical record as magister equitum under Emperor Julian.^[2] He rose to the position of magister militum during the reign of Emperor Jovian (363-364) and retained his rank under Valentinian I (364-375). Jovinus successfully repelled several Alemanni incursions, notably in 366 at Scarponna. He was elected consul in 367, together with his colleague Lupicinus.

Jovinus served as magister equitum in Gaul under Emperor Julian. Julian's successor Jovian wanted to give the posting to one of his own appointees, but his attempt to remove Jovinus in 363 caused the Gallic army to mutiny. Jovinus pacified the soldiers and refused their attempts to proclaim him as emperor, and Jovian gratefully promoted him to magister militum.^[3][4] In 366, he engaged the Alamanni, who had crossed the Rhine, in three notable battles: one at Scarponna (Dieulouard), another along a river^[5] (probably the Moselle), and a final encounter at Châlons-en-Champagne. In 367, he became consul of the Western Roman Empire alongside Lupicinus.

After converting to Christianity, Jovinus sponsored the construction of the church of Saint-Agricole and Saint-Vital on the site of the present abbey church of Saint-Nicaise de Reims. He was buried in this church in 370 in a white Marmara marble sarcophagus imported from Italy. This sarcophagus measures 1.48m x 2.85m x 1.33m and weighs approximately 2 metric tons. On its front is a relief of a hunting scene, with Jovinus shown on horseback, spearing a lion. It has been in the Musée d'Archéologie de Saint-Rémi in Reims since 1958. However, its attribution to Jovinus has been disputed since 1880.^{[citation needed]}

Jovinus is also credited with the founding of Joigny (Joviniacum) and Joinville.
