The Mürzsteg Alps or Mürztal Alps (German: Mürztaler or Mürzsteger Alpen) are a mountain range in the Eastern Alps (Northern Limestone Alps), which lie in the Austrian state of Styria, with a small part of the range in Lower Austria.

The highest peak is the Hohe Veitsch (1,981 m above sea level (AA)) in the centre of the group, while largest massif is the Schneealpe (1,903 m above sea level (AA)) in the northwest, near the Rax.

The range is part of the Styrian-Lower Austrian Limestone Alps and is separated from its neighbouring groups by the Mürz valley (part of the tectonically active Mur-Mürz Furrow), the upper reaches of the Mürz (main settlement: Mürzsteg) and the road over the Styrian Seeberg Pass.

The majority of its rocks date to the Triassic period and include Wetterstein Dolomite, Hallstatt Limestone and Mürztal strata (dark, hornstein-dominated limestones and marls with foraminifers, brachiopods and other fossils).

The south of the range belong to the greywacke zone (rocks from the New Palaeozoic and the Lower Triassic).
