Schloss Fuschl is a castle in the gemeinde of Hof bei Salzburg, in the Land Salzburg in western Austria. It stands on a peninsula at the western end of Lake Fuschl, a glacier lake. It was built in about 1450 by the Prince-Archbishops of Salzburg, who used it as a hunting lodge.

In 1816, the prince-bishopric of Salzburg was dissolved and the property passed to the Austrian state. It fell into disrepair.

By the 1930s, it was owned by Gustav Edler von Remiz and his wife Hedwig, who lived there. Remiz was a member of the Thyssen dynasty. He was a supporter of the Fatherland Front, so was imprisoned by the Nazis in Dachau, where he died. His property was confiscated, and Schloss Fuschl became the summer residence of Joachim von Ribbentrop, Nazi foreign minister, who used it for diplomatic receptions for Germany's allies.

In 1955, the property was restored to the von Remiz family. It was used as a location for the film Sissi.

It was made into a hotel in the 1950s. It retains a collection of old master paintings.
