Blanchetown is a small township in South Australia, on the (west) bank of the Murray River, 130 kilometres (81 mi) northeast of Adelaide. The Blanchetown Bridge is the westernmost of the four crossings of the Sturt Highway over the Murray River. During the nineteenth century it was an important transportation centre on the lower Murray. In the early 21st century, Blanchetown has been described as "a strange mixture of historic buildings and temporary shacks built by holidaymakers on the banks of the river". Blanchetown is widely regarded as the entrance to the Riverland district.

The Murray River is a river in Southeastern Australia. It is Australia's longest river at 2,508 km (1,558 mi) extent. Its tributaries include five of the next six longest rivers of Australia. Together with that of the Murray, the catchments of these rivers form the Murray–Darling basin, which covers about one-seventh the area of Australia. It is widely considered Australia's most important irrigated region.
