Stecknadelhorn, Mountain summit in Valais, Switzerland.

Stecknadelhorn is a 4,240-metre summit on the Nadelgrat, a high ridge in the Mischabel range of the Pennine Alps, between Saas Fee and Täsch in Valais. It is counted as a separate four-thousander and is usually crossed while traversing the Nadelgrat. The Mischabel range culminates at the Dom (4,546 m).

Oscar Eckenstein and the guide Matthias Zurbriggen made the first ascent on 8 August 1887. The Stecknadelhorn is usually not climbed on its own but crossed while traversing the Nadelgrat, the high ridge above Saas Fee and the Mattertal.

The name Stecknadelhorn refers to the mountain's needle-like pointed shape that defines the Mischabel group. Local climbers and guides use this distinctive feature as a landmark when navigating the surrounding peaks.

Access to the peak requires hiking to the Mischabel Hut at 3,340 meters, which takes about four hours from Saas Fee with roughly 1,550 meters of elevation gain. The route demands sure-footedness, good weather, and climbing experience for safe conditions.

The Stecknadelhorn is not usually climbed on its own: most parties reach it while traversing the Nadelgrat, the north–south ridge above Saas Fee. Its 4,240 m summit is counted as a separate four-thousander, and the Mischabel range it belongs to culminates at the Dom (4,546 m).
