Camden South is a suburb of the Macarthur Region of Sydney in the state of New South Wales, Australia in Camden Council.

The area now known as Camden South was originally home to the Muringong, the southernmost of the Darug people, and the Gandangara people of the Southern Highlands.

In 1805, wool pioneer John Macarthur was granted 5,000 acres (20 km2) at Cowpastures (now Camden).

After the land was cleared, it was used for farming for most of the next 200 years until Sydney's suburban sprawl reached the town of Camden and modern suburbs like Camden South were subdivided into housing blocks.

It sits within the state electorate of Camden, represented by Labor's Geoff Corrigan, the former Mayor of Camden, and the federal electorate of Macarthur, represented by Liberal's Pat Farmer, the former ultra-marathon runner.
