A wine region centred on the town of Coonawarra in the Limestone Coast zone of South Australia, about 380 km southeast of Adelaide, close to the border with Victoria. It is known for the Cabernet Sauvignon wines produced on its 'terra rossa' soil.

Being just 60 km from the sea, Coonawarra has a somewhat maritime climate not dissimilar to Bordeaux. Coonawarra is synonymous with Cabernet Sauvignon, full of plum and blackcurrant fruit, so much so that success with other grape varieties is often overlooked. In the early days Shiraz was the most widely planted grape, and it still produces some star wines. The limestone geology also suits Chardonnay, Riesling and Sauvignon Blanc.
