Deuriopus (Strabo: Δευρίοπος Deuriopos; Stephanus of Byzantium: Δουρίοπος Douriopos) was a subdivision of Paionia, in what is today the Republic of Macedonia. Its exact limits are unclear, but it is known that it contained lands around the river Crna (ancient Erigonus). The towns Bryanium (Bruanion in ancient Greek) and Styberra (also known as Stuberrha) (near today's Prilep) were located in Deuriopus. According to Livy, Philip V of Macedon founded the city of Perseis in Deuriopus, named after his eldest son, Perseus.
