The Vipava (in Slovene) or Vipacco (in Italian) or Wipbach / Wippach (in German) is a river that flows through western Slovenia and northeast Italy. The river is 49 kilometres (30 mi) in length. After entering Italy it joins the Isonzo/Soča in the Municipality of Savogna d'Isonzo. This is a rare river with a delta source, formed by nine main springs. The Battle of the Frigidus was fought near the river, which was named Frigidus ('cold') by the Romans.
