Padthaway (population 218) is a town on the Riddoch Highway in the south-east of South Australia, halfway from Keith to Naracoorte. The name is derived from the Potawurutj Aboriginal name for Good Water.
Padthaway is in the Tatiara District Council, the state electorate of MacKillop and the federal Division of Barker.
Padthaway is also the name of a wine region surrounding the town. It is home to a variety of large commercial vineyards (the oldest established in 1964), but only a few cellar doors. Many of Australia’s best known wine labels grow grapes here.
