The Hörnli Hut (German: Hörnlihütte) is a mountain hut located at the foot of the north-eastern ridge (Hörnli Ridge) of the Matterhorn. It is situated at 3,260 metres (10,700 ft) above sea level, a few kilometers south-west of the town of Zermatt in the canton of Valais in Switzerland. It was built by the Swiss Alpine Club in 1880. It is also known as Berghaus Matterhorn.
The hut is accessible to good hikers, from the cable car station of Schwarzsee (or from Zermatt) a marked trail leads to the ridge and then to the hut. It is used to climb the Matterhorn on the normal route. The Solvay Hut lies also higher on the same ridge, but can be only used in case of emergency.
