'riparian Dacia') was the name of a Roman province in the northern Balkan peninsula, immediately south of the Middle Danube.

[2] It was a district less urban than neighbouring Dacia Mediterranea and more militarized; "military camps and forts, rather than cities, were typical of the province".

[1] The Roman emperor Aurelian (r. 270–275) abandoned the province of Roman Dacia established by Trajan (r. 98–117) in 106 AD on the northern bank of the river, and created the two new "Dacias" between the existing provinces of Moesia Prima (upstream) and Moesia Secunda (downstream).

Dacia Ripensis flourished in the mid-4th century, and some forts on the northern bank of the Danube were recovered by the Romans.

Ratiaria was established as the capital of Dacia Ripensis (it was previously a colony founded by Trajan located within Moesia Superior) and served both as the seat of the military governor (or dux) and as the military base for the Roman legion XIII Gemina.
