Eden Valley gives its name to a wine growing region that shares its western boundary with the Barossa Valley. The region is of similar size to the Barossa Valley, and is well known for producing high quality riesling and shiraz wines. Englishman Joseph Gilbert planted the first Eden Valley vineyard, Pewsey Vale, in 1847. Within the Eden Valley region there is a sub-region called High Eden which is located higher in the Barossa Ranges, giving cooler temperatures.
Eden Valley is in the Barossa Council local government area, the state electoral district of Schubert and the federal Division of Wakefield.
