Europa (Greek: Εύρώπη) was a Roman province within the Diocese of Thrace.

Established by Roman Emperor Diocletian (284–305),[1] the province largely corresponds to what is modern day European Turkey.

The province's capital was initially Arcadiopolis and subsequently Perinthus (later known as Heraclea; modern Marmara Ereğlisi).

Along the coast of the Sea of Marmara were the cities of Perinthus (the capital; later known as Heraclea), Selymbria, Raidestus, and Callipolis.

On the coast of the Aegean and at the mouth of the Hebrus river in the Melas Gulf was the city of Aenus (Thrace).
