A small settlement lying on the transcontinental railway line in the Australian state of South Australia. It lies at the junction of the Stuart Highway to Alice Springs and the road to Woomera, Roxby Downs and Andamooka.

Where is it?: Outback South Australia. 435 km north of Adelaide; 166 km north west of Port Augusta; 7 km south west of Woomera..

The Ghan railway line traverses around the shores of Lake Hart, to the west of Pimba

Pimba is surrounded by the Woomera Rocket Range and because of this, it is illegal to leave Stuart Highway on your way in and out of the town as it passes through the Wommera Prohibited Area. The Federal Government is presently in the process of opening up the Woomera Prohibited Area in South Australia to minerals exploration and resources development.

There is an iconic roadhouse, named "Spud's Roadhouse", which sells fuel and general shop items and meals and has accommodation. At the 2006 census, Pimba had a population of 50.

Despite the small population, the Indian Pacific (running between Sydney and Perth) and Ghan (running between Adelaide, Alice Springs and Darwin, trains still call at Pimba Siding on request; both trains service the town twice a week in each direction.
