Chowilla is a locality in the Australian state of South Australia, located on the northern side of the Murray River about 250 kilometres (160 miles) to the north-east of the capital city of Adelaide and about 40 kilometres (25 miles) to the north-east of the town of Renmark, and which is bounded by the border with New South Wales in the east.

[1][8] There are three historic sites within Chowilla which have been listed on the South Australian Heritage Register: the Suicide Bridge (or Lunatic Bridge), including nearby remnant posts from the New South Wales-South Australia telegraph line and Littra House, both near Lake Littra, and Todd's Obelisk, near the New South Wales border.

[9][10][11] The 2016 Australian census which was conducted in August 2016 reports that Chowilla had a population of zero.

[2] This was because the residents of Chowilla, James, Kerrie, Emily and Sophie Robertson were not provided with census documents.

Chowilla is located within the federal Division of Barker, the state electoral district of Chaffey, the Pastoral Unincorporated Area of South Australia and the state's Murray and Mallee region.
