Marion is a suburb in the City of Marion, around 10 kilometres (6.2 mi) south-west of the city centre of Adelaide, the capital of South Australia. Founded as a rural village in 1838 on the banks of the Sturt River, Marion was found to have rich soil and the population expanded rapidly. Colonel William Light laid out the plan for the village, as he had done with the City of Adelaide itself.

The Sturt River, also known as the Sturt Creek and Warri Parri (Warriparri) in the Kaurna language, is a river located in the Adelaide region of the Australian state of South Australia.
