Dardania (; Ancient Greek: Δαρδανία; Latin: Dardania) was a Roman and Byzantine (Eastern Roman) province in the Balkans, initially an unofficial region in Moesia (87–284), then a province administratively part of the Diocese of Moesia (293–337). It was named after the ancient tribe of Dardani which inhabited the region prior to the Roman conquest (28 BC–6 AD).
During the administrative reforms of Diocletian (244 - 311) and Constantine I (272 – 337), the Diocese of Moesia was created, encompassing most of the central Balkans and the Greek peninsula. After a few years, however, the diocese was split in two, forming the Diocese of Macedonia and the Diocese of Dacia, encompassing the provinces of Dacia Mediterranea, Moesia Inferior, Dardania, Praevalitana and Dacia Ripensis.
Since 238, Moesia was constantly invaded or raided by the Carpi, and the Goths, who had already invaded Moesia in 250. Hard pressed by the Huns, the Goths again crossed the Danube during the reign of Valens (376) and with his permission settled in Moesia.
The area remained part of the Byzantine empire until the late early 7th century when the Slavic migration destroyed Byzantine authority in most of the Balkan peninsula. Since then Dardania ceased to exist as separate administrative entity.
Dardania's largest towns by the time it was part of the municipium Dardanicum (in modern Socanica near the Ibar valley) was connected with the workings (metalla Dardanica). Dacians lived in Dardania in their city Quemedava.
