The Northern Styrian Alps (Steirische Nordalpen in German) is the proposed name for a subdivision of mountain ranges in an as-yet-unadopted classification of the Alps located in Austria.
Administratively the range belongs to the Austrian state of Styria and, marginally, to Upper Austria and Lower Austria.
The whole range is drained by the Danube river.
According to SOIUSA (International Standardized Mountain Subdivision of the Alps) the mountain range is an Alpine section, classified in the following way:
main part = Eastern Alps
major sector = Northern Limestone Alps
section = Northern Styrian Alps
code = II/B-26
The range is divided in two Alpine subsections:
Ennstal Alps - SOIUSA code:II/B-26.I;
North-eastern Styrian Alps - SOIUSA code:II/B-26.II;These subsections are further subdivided in supergroups as it follows:
supergroup Haller Mauern - SOIUSA code:II/B-26.I-A,
supergroup Gesäuse - SOIUSA code:II/B-26.I-B,
supergroup Eisenerzer Alpen - SOIUSA code:II/B-26.I-C.
North-eastern Styrian Alps:
supergroup Hochschwabgruppe - SOIUSA code:II/B-26.II-A,
supergroup Mürzsteger Alpen - SOIUSA code:II/B-26.II-B,
supergroup Rax-Schneeberg-Gruppe - SOIUSA code:II/B-26.II-C.
