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, of which 45 km in Slovenia. 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. It has a pluvial-nival regime in its upper course and a pluvial regime in its lower course.
