Vipava (pronounced [ʋiˈpaːʋa] ⓘ; Italian: Vipacco, German: Wippach[2]) is a town in western Slovenia.

In the late 8th century, the Vipava Valley was included in the Frankish Empire and the Christianization of Slovenes started.

Between 1340 and 1355, Vipava and its surroundings were constantly contended between the Counts of Gorizia, the Patriarches of Aquileia and the Habsburg Duchy of Carniola.

After a short Venetian interim, Vipava fell under the Habsburg domain in 1501 and in 1535 it was included in Carniola.

It remained part of Carniola until 1918, when it was occupied by the Italian troops and annexed to the Kingdom of Italy.

During World War II, the entire area became an important center of Partisan resistance.

In 1945, it was liberated by Partisan troops and in 1947 it became part of the Socialist Federal Republic of Yugoslavia, and of independent Slovenia in 1991.

The Vipava Field Mass Grave (Grobišče Vipavsko polje) extends south of the dairy to Močilnik Creek.

The parish church in the town is dedicated to Saint Stephen and belongs to the Diocese of Koper.
