The Wiedersberger Horn is a mountain in the Alpbachtal valley in Austria.

The Wiedersberger Horn is accessible from the Alpbachtal via cableways and the mountainsides are used as a skiing area.

In winter it may be climbed without difficulty in safe snow conditions.

From the top station of the highest lift in the ski area (2,025 m) there is a path to the summit facilitated by step-like wooden beams.

On the wooden summit cross is a plaque with the inscription: Dem Herrgott und der Heimat in treuer Einigkeit im Ottober des Heiligen Jahres 1933 errichtet.
