Dacia Mediterranea (Mediterranean Dacia; Greek: Επαρχία Δακίας Μεσογείου, Eparchia Dakias Mesogeiou) was a late Roman province, split off from the former Dacia Aureliana by Roman emperor Diocletian (284-305). Serdica (or Sardica; later Sradetz or Sredets, now Sofia) was the province capital.
Scholars have different opinions regarding the date and circumstances of the foundation of Dacia Mediterranea as a separate province.
