The Gamshag is a mountain in the Kitzbühel Alps in the Austrian state of Tyrol whose summit reaches a height of 2,178 m (AA).

The Gamshag is located northwest of the Torsee lake, the source of the River Saalach.

The prominent peak of the Tristkogel (2,095 m (AA)) rises to the northeast.

The Gamshag is easily accessed over well-signposted hiking trails both from the west from Jochberg as well as from the Saalach valley to the east.

In winter the mountain can also be climbed as part of a ski tour.
