Eichberg is a former municipality in the district of Hartberg-Fürstenfeld, in the Austrian state of Styria. It lies in the eastern part of Styria, a region of rolling hills and farmland near the border with Burgenland.
As part of the 2015 Styria municipal structural reform, Eichberg was merged into the municipality of Rohrbach an der Lafnitz and ceased to exist as an independent municipality. Since then it has been a cadastral community within that larger municipality rather than a separate administrative unit.
Its administrative affiliation places it within the Hartberg-Fürstenfeld district, one of the districts that make up the state of Styria. The village is named after the Eichberg, the hill from which it takes its name.
