Pewsey Vale is a locality east of the southern Barossa Valley in the western part of the Eden Valley of South Australia. It was first established as a sheep station pastoral run in the early years of the colony by Joseph Gilbert. Gilbert named his run Pewsey Vale in 1839 after the Vale of Pewsey in Wiltshire, England, where he was born. It was originally to be called Karrawatta, however this name was easily confused with the neighboring Tarrawatta.
