The Nadelhorn (4,327 m) 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 (German: Nadel) when seen from the north. The other summits on the Nadelgrat are the Stecknadelhorn , the Hohberghorn , the Dürrenhorn and the Lenzspitze .

It was first climbed by Franz Andenmatten, Baptiste Epiney, Aloys Supersaxo and J. Zimmermann on 16 September 1858.
