The Ennstal Alps (German Ennstaler Alpen), the Alps of the Enns valley, are a mountain range of the Northern Limestone Alps System. They are located primarily in the Austrian state of Styria, and also into the state of Upper Austria.

The most famous scenery in the Ennstal Alps is the Gesäuse, a valley where the Enns river cuts through the limestone.

The Ennstal Alps range is defined by:

• the lineup of Liezen, Pyhrn Pass, and Windischgarsten on the west.
• Hengst Pass and the Laussabach on the north.
• the lineup of the River Enns (from Altenmarkt bei Sankt Gallen to Hieflau), Erzbach, and Vordernbergerbach on the east
• the lineup of the Mur river (from Leoben to Sankt Michael in Obersteiermark), Liesing, and Palten on the south

Mountain groups that are part of the Ennstal Alps include:

• Haller Mauern (highest summit: Großer Pyhrgas, 2,244 m)
• Gesäuse Mountains, including the Buchstein Group (2,224 m), Reichenstein Group (2.251 m) and Hochtor Group (Hochtor, 2,369 m) and the Lugauer (2,217 m).
• Eisenerzer Reichenstein 2,165 m (Eisenerz Alps), with the preceding massifs of Reiting (including the Gößeck its main summit, 2,214 m) (in the south) and the Kaiserschild (2,105 m) in the north.

The Ennstal Alps range is pierced in the north by the Enns river. The Enns river valley name in German is Gesäuse. The valley is accompanied by the only roads and railway lines that run through the Ennstal Alps.
