Patteriol, Mountain summit in Verwall Alps, Austria.

Patteriol is a 3,056 m summit in the Fasulkamm chain of the Verwall Alps in Tyrol, Austria, built mainly of biotite granite gneiss. Its main peak is joined by the South summit or Pfeilerkopf (2,884 m), the Horn (3,003 m) and, about 1 km north, the Kleiner Patteriol (2,590 m).

The mountain was first climbed around 1860 by geodesists, hunters, and military personnel who traced an initial route up its slopes. This early ascent established the foundation for routes still used by climbers today.

The Patteriol is sometimes called the "Matterhorn of Verwall" because of its shape. The name appears in Alpine writing rather than in local dialect use, and it points to the steep, pointed profile seen from the Fasultal. The Konstanzer Hütte below the mountain serves as its base for climbers and hikers.

The ascent starts from Konstanzer Hütte and takes several hours on mixed terrain with exposed sections. Experience with rock scrambling and good balance are needed for the steeper passages on the route.

The Patteriol has three named subsidiary summits: the South summit or Pfeilerkopf (2,884 m), the Horn (3,003 m) and, about 1 km north of the main summit, the Kleiner Patteriol (2,590 m). The main summit reaches 3,056 m; older literature gives 3,059 m. Its rock is biotite granite gneiss.
