The East Styrian Hill Country or East Styrian Hills (German: Oststeirisches Hügelland or Oststeirisches Riedelland), is a rolling, hill country region, known as Hügelland, in the southeast of the Austrian state of Styria.
The East Styrian Hill Country is part of the Alpine Foreland in the East and Southeast and extend over large parts of East Styria and Southeast Styria. They are characterised by elongated hill ridges or interfluves (Riedel). They are bounded in the west and south by the River Mur and in the north by the Prealps East of the Mur, especially the eastern Graz Uplands, the prominent Kulm massif and the Joglland with its peak, the Masenberg. To the east it is bounded by the Lafnitz river.
The East Styrian Hills cover an area of about 50 x 80 km, but continue as a landscape type geologically and morphologically:
Most of the valleys in the entire region run southwards to southeastwards, which gives the orography its typical divisions. The region is drained by the Mur as well as the waters of the Raab and Feistritz , and the valley of the Lafnitz forms the boundary.
