The Klein Matterhorn is a peak of the Pennine Alps, overlooking Zermatt in the Swiss canton of Valais. At 3,883 metres (12,740 ft) above sea level, it is the highest place in Europe that can be reached by aerial tramway or gondola lift, as well as by any other means of transport. The Klein Matterhorn is part of the Breithorn massif and overlooks on its south side the almost equally high flat glacier named Breithorn Plateau, just north of the international border with Italy. The name "Klein Matterhorn" is a reference to its much larger neighbour, the Matterhorn, which lies 7 km (4.3 mi) away across the Theodul Pass.

The Pennine Alps French: Alpes Pennines, German: Walliser Alpen, Italian: Alpi Pennine, Latin: Alpes Poeninae), sometimes referred to as the Valais Alps, are a mountain range in the western part of the Alps. They are located in Italy and Switzerland (Valais).
