Eisbach is a former municipality in the district of Graz-Umgebung, in the Austrian state of Styria. It lies in the federal state of Styria in southeastern Austria, within the district that surrounds the city of Graz.
Since the 2015 Styria municipal structural reform, Eisbach is no longer an independent municipality. It has been part of the municipality of Gratwein-Straßengel since that reform, which merged a number of previously separate communities in the district.
