The Guduscani or Goduscani (Croatian: Guduščani, Gačani) were a tribe whose location and origin on the territory of early medieval Croatia remains a matter of dispute. According to different hypotheses, they were a tribe or clan of Croat, Slavic, Avaric or Gothic origin that was located around present-day Gacka (Lika), between upper Kupa River and the Dalmatian coast, or that were inhabitants around the river Guduča near the Bribir region.
