Schloss Ebenthal, Protected castle in Ebenthal, Austria.

Schloss Ebenthal is a castle in Ebenthal, Austria, featuring classic Austrian architectural elements with stone components and period details. The property sits within the Marktgemeinde Ebenthal region and is managed today as a protected cultural monument.

A 1371 charter names a "Veste Ebenthal"; by 1478 it was recorded as "öde und zerbrochen", and in 1487 Jakob Grabner zu Rosenburg held it. Andreas Josef Graf Koháry acquired the estate in 1732 and had the present Baroque palace built from 1733. The Sachsen-Coburg-Koháry family owned it until 1970; it is now privately owned.

The castle is also known as Schloss Coburg after the Saxe-Coburg and Gotha-Koháry family, who owned it until 1970. August von Sachsen-Coburg und Gotha-Koháry, a son of the Koháry heiress Maria Antonie Gabriele, died here on 26 July 1881. The Koháry archive in Banská Bystrica preserves building records, including a sketch dated 1736.

Schloss Ebenthal stands in the market municipality of Ebenthal in the Gänserndorf district of Lower Austria, in the Weinviertel region northeast of Vienna, not near Klagenfurt in Carinthia. It has been privately owned since 1970 following several sales, so the grounds and interiors are not open to the public as a museum. Visitors view the baroque main facade from the public street in the village; there is no visitor parking area or on-site information point.

The building is also known as Schloss Coburg, after the Saxe-Coburg and Gotha-Koháry family who owned it until 1970. August von Sachsen-Coburg und Gotha-Koháry, a son of the house, died here on 26 July 1881. In 1918 Tsar Ferdinand I of Bulgaria sought refuge here but was refused by his brother-in-law Emperor Karl I.
