Life

Demetrius of Sirmium was a martyr in the city of Sirmium in Pannonia, today Sremska Mitrovica in Serbia, a saint of the undivided Church.

The Syriac Martyrology of 411 commemorates him on 9 April, by the Julian calendar (old style). The Latin Hieronymian Martyrology, of the same origin, says that he was a deacon. No other account of his life or death survives; he should not be confused with the Great Martyr Demetrius of Thessalonica.
