Auersbach is a former municipality in the district of Südoststeiermark, in the Austrian state of Styria. It is located in the southeastern part of the country, within the region known as Styria.
Since the 2015 Styria municipal structural reform, Auersbach is no longer an independent municipality and has been part of the municipality of Feldbach. The reform reorganized municipal boundaries across the state, merging smaller communes into larger administrative units.
