Leigh Creek (formerly Leigh's Creek) is a coal-mining town in eastern central South Australia. At the 2011 census, Leigh Creek had a population of 550.
Situated to the west of the northern Flinders Ranges, the current town is 13 km further south than the original town—it was moved in 1982 to allow the expansion of the mine. As a result, most facilities and buildings in the town are only a little over thirty years old, and with relatively modern designs.
The mine and associated railway station are named Telford.
