Gossendorf is a former municipality in the district of Südoststeiermark, in the Austrian state of Styria. It lies in the southeastern part of the country, within the broader region known as Styria.
Since the 2015 Styria municipal structural reform, Gossendorf is no longer an independent municipality and has been part of the municipality of Feldbach. The reform reorganized many smaller municipalities across the state, merging them into larger administrative units.
Its status today is therefore that of a former municipality and a component locality of Feldbach, rather than a separate administrative entity.
