Argidava was a Dacian fortress town close to the Danube, inhabited and governed by the Albocense. Located in today's Vărădia, Caraș-Severin County, Romania.
After the Roman conquest of Dacia, it became a military and a civilian center, with a castrum (Roman fort) (see Castra Arcidava) built in the area. The fort was used to monitor the shores of the Danube.
