Ebermannstadt Castle (German: Burgstall Ebermannstadt) is a levelled medieval motte castle on the heights of the Franconian Jura at Wacht Knock (470 m above sea level (NHN)), west of the town of Ebermannstadt in the county of Forchheim in the south German state of Bavaria.

The fortification dates to the 11th century and was probably a refuge castle.

It has an area of about 2.5 hectares and occupies a hill plateau with a diameter of over 30 metres and is surrounded by the bailey which measures 120 by 100 metres.

The motte, which has been levelled, is oval in shape and was up to five metres in height.

It is surrounded at a distance of 22 metres by a horseshoe-shaped outer rampart.
