Piz Scerscen (Romansh, Italian: Monte Scerscen, formerly Monte Rosso di Scerscen), culminating at 3,970 m above sea level, is one of the highest peaks in the Bernina Range , straddling the border between Switzerland and Italy. It is a satellite peak of Piz Bernina , joining it by its north-east ridge via a 3,882 m pass. Its name means 'the circular mountain' ('Scerscen' is pronounced cherchen).

The mountain has a prominent secondary summit called the Schneehaube (3,875 m).

The first ascent of Piz Scerscen was by Paul Güssfeldt, Hans Grass and Caspar Capat on 13 September 1877 via the north-west spur, descending the same way. This is the well-known Eisnase route, involving a 100-metre ice pitch of between 60 and 70°, although its precise length and steepness are debated.[1] This was the route followed by Walter Risch on the first solo ascent of the mountain in 1924.
