The Coonawarra wine region is a wine region centred on the town of Coonawarra in the Limestone Coast zone of South Australia. It is known for the Cabernet Sauvignon wines produced on its "terra rossa" soil. Coonawarra is an Aboriginal word meaning "Honeysuckle". It is about 380 km southeast of Adelaide, close to the border with Victoria. Coonawarra's terra rossa soil is one of the notable terroirs of the New World, covering an area of just 15 km x 2 km north of Penola.

Coonawarra is synonymous with Cabernet Sauvignon, full of plum and blackcurrant fruit, so much so that successes with other grape varieties is overlooked. In the early days Shiraz was the most widely planted grape, and it produces some star wines such as Wynns Coonawarra Estate Michael Shiraz (formerly Michael Hermitage). The limestone geology also suits Chardonnay, Riesling, and Sauvignon blanc.
