The Northern Limestone Alps (Deutsch. Nördliche Kalkalpen) are the ranges of the Eastern Alps north of the Central Eastern Alps located in the alpine countries of Austria, and Germany. The distinction from the latter group, where the higher peaks are located, is based on differences in geological composition. If viewed on a west-east axis, the Northern Limestone Alps extend from the Bregenzerwald in Vorarlberg, Austria in the west through the German/Austrian federal-states of Bavaria, Tyrol, Salzburg, Upper Austria, and Styria to the Wienerwald in Lower Austria. They end in the city-state of Vienna in the east.
The highest peaks in the Northern Limestone Alps are Parseierspitze (3,036 metres) in the Lechtal Alps, and Hoher Dachstein (2,996 m) in the Dachstein massif.
