Piz Sardona (or Surenstock) is a mountain in the Glarus Alps, located on the border between the cantons Glarus and St. Gallen. The 3,056 metres high mountain overlooks the valleys of Elm (Glarus) and Calfeisen (St. Gallen). Less than one kilometre south of the summit lies the tripoint (3,000 metres) between the cantons of Glarus, St. Gallen and Graubünden. The summit itself is the northernmost point above 3,000 metres in Switzerland.
The massif is covered by a few small glaciers, the Sardonagletscher lying near the summit on the east side.
Piz Sardona is located within the Glarus thrust, a geologic UNESCO world heritage site, named Swiss Tectonic Arena Sardona.
