Tatiara District Council is a local government area located in south-eastern South Australia. The name Tatiara is said to mean "the good country", a phrase which dates back to the area's first inhabitants, the Bodaruwitj people. It is one of the largest local government areas in South Australia at 6,476 km2 (2,500 sq mi). The district's economy is based primarily on agriculture, with cereal crops such as wheat, barley and oats and with livestock such as sheep, cattle and pigs prominent.

The Limestone Coast is a name used since the early twenty-first century for a South Australian government region located in the south east of South Australia which immediately adjoins the continental coastline and the Victorian border. The name is also used for a tourist region and a wine zone both located in the same part of South Australia.
