Eppenstein is a former municipality in the district of Murtal in the Austrian state of Styria.

[2] Eppenstein lies in the Lavanttal Alps stretching along the narrow valley of the Granitzenbach creek, which runs from the Upper Mur valley in the north up to the Obdach Saddle pass and the Lavant Valley valley in Carinthia.

The former municipal area comprised the cadastral communities of Mühldorf, Schoberegg, and Schwarzenbach.

Later held by Habsburg ministeriales like the Graben von Stein family, it was rebuilt in a Gothic style around 1478.
