The Wallackhaus is a mountain hut located on the Grossglockner High Alpine Road in the Austrian state of Carinthia.

Immediately to the east is the Großglockner - Heiligenblut ski area.

The Wallackhaus was created in 1930 from a canteen for the construction workers on Großglocknerstrasse, south of the tunnel on the Hochtor Pass.

The house was named after the engineer Franz Wallack, who was commissioned to plan the road.

After the construction work was completed, the house developed into an inn serving tourism in 1935.
