The Kalkkögel are a mountain chain that is part of the Stubai Alps in Tyrol, Austria.

The highest point of the Kalkkögel is the Schlicker Seespitze which reaches a height of 2,804 m (AA); its easternmost mountain is the Ampferstein.

The Kalkkögel consist of Mesozoic sediments, like those that occur elsewhere in the Stubai Alps, west of the Wipptal valley, around the Serles crest or in the area of the Tribulaune.

In the region of the Kalkkögel, there are sediments from the boundary of the Permian-Triassic to the Norian of the upper Triassic, which lie on its crystalline bedrock.

In this layer, which is at most a few tens of metres thick, are iron ore deposits, the most important of which were quarried south of the Burgstall and was the basis of the tool industry in the Stubaital that still exists today.
