Dacia Mediterranea (Mid-land Dacia; Greek: Δακία Μεσόγειος, romanized: Dakia Mesogeios) was a late antique Roman province, whose capital city was Serdica (or Sardica; later Sradetz or Sredets, now Sofia).

[1] Lying immediately south of Dacia Ripensis, the province was governed by a Consularis.

[3] During this time he also strengthened the fortifications of various cities in the province, including Serdica, Naissus, Germania and Pautalia.

[4] Dacia Mediterranea was caught up in the devastation of the Avar and Slav invasions of the late 6th and early 7th centuries, and was lost at the same time as the Diocese of Dacia, although pockets of the province continued to remain in Byzantine hands, such as Serdica and its immediate surrounds.

These south-eastern remnants were eventually absorbed into the Theme of Thrace by the late 7th century.
