The Northern Limestone Alps (German: Nördliche Kalkalpen), also called the Northern Calcareous Alps, are the ranges of the Eastern Alps north of the Central Eastern Alps located in Austria and the adjacent Bavarian lands of southeastern 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 Rhine valley and the Bregenz Forest in Vorarlberg, Austria in the west extending along the border between the German federal-state of Bavaria and Austrian Tyrol, through Salzburg, Upper Austria, Styria and Lower Austria and finally ending at the Wienerwald at the city-limits of Vienna in the east.

The highest peaks in the Northern Limestone Alps are the Parseierspitze (3,036 metres (9,961 ft)) in the Lechtal Alps,^[1] and the Hoher Dachstein (2,996 metres (9,829 ft)). Other notable peaks in this range include the Zugspitze, (2,962 metres (9,718 ft)), located on the German-Austrian frontier and listed as the highest peak in Germany.
