The Nadelhorn is a mountain in the Pennine Alps in Switzerland. It is the highest point on the Nadelgrat, a high-level ridge running roughly north–south above the resort of Saas-Fee to the east, and the Mattertal to the west. Its three ridges join to form a sharp-pointed summit, which looks like a needle when seen from the north. The other summits on the Nadelgrat are the Stecknadelhorn and Hohberghorn.
