The Alpstein are a subgroup of the Appenzell Alps in Switzerland. The Alpstein massif is in Appenzell Innerrhoden, Appenzell Ausserrhoden and St. Gallen.
Despite it being rather low when compared to other Alpine peaks – the highest mountain is the Säntis at 2502 metres – the Alpstein, due to their northern "outpost" position only a short distance from Lake Constance (nearly 30 km) are relatively tall when compared to the surrounding area. The range also includes the Altenalp Türm as the northernmost summit above 2,000 metres in Switzerland.
