Gothiscandza was according to the 6th century Goth scholar Jordanes, the first settlement of the Goths after their migration from Scandinavia (Scandza). One interpretation of the name is gutisk-andja, "gothic end (or frontier)" (cf. Scandza <- Scandia).

Gothiscandza was located at the mouth of the Vistula, and this location was given as the land of the Gutones (Pliny the Elder) or Gotones (Tacitus). The names given by Pliny and Tacitus appear to be identical to *Gutoniz, the reconstructed Proto-Germanic form of Gutans, the Goths' name for themselves.

Gothiscandza is identified with the Wielbark Culture, and there is archaeological evidence of Scandinavian influence in the area during the Nordic Bronze Age and the Pre-Roman Iron Age[1]. However, the degree of influence during the first decades of the 1st century AD is contested, but the most salient component is the introduction of Scandinavian burial traditions such stone circles.

The legend of Dag the Wise may convey traditions of attacks by the Suiones in the 2nd or 3rd century. In Scandinavian sources, the territory is called Reidgotaland, a name that followed the Goths during their migrations in the Norse sagas.
