1,641 m [5,384 ft]) is a high mountain pass in the Central Eastern Alps in Austria between Rennweg am Katschberg in the state of Carinthia and Sankt Michael im Lungau in Salzburg.

It connects the Carinthian Katsch Valley in the south with the historic Lungau region of Salzburg (present-day Tamsweg district) and the Mur river in the north, from where the road leads further on to the Radstädter Tauern Pass.

Katschberg also separates the Ankogel Group of the Hohe Tauern range in the west from the Nock Mountains, part of the Gurktal Alps, in the east.

The steepest and most difficult runs are from the Aineck to Katschberg valley - the black piste: Diretissima with up to 100% incline gradient at the unpisted first section making it one of the steepest runs in Austria – 3 kilometres (1.9 mi), and the Tschaneck "Nord" run (black piste with 55% incline gradient – but also suitable for families – 1.8 kilometres [1.1 mi]).

These days, there is a 200-km-wide hiking trail network as well as numerous summer activities and accommodations in the region.
