Schloss Garath, Architectural heritage monument in Garath, Düsseldorf, Germany.

Schloss Garath is a manor house in Düsseldorf with thick stone walls and medieval building details that was occupied and used over a long period. The basic structure comes from the medieval period, but was rebuilt and expanded several times in later eras.

Garath was likely a knight's seat as early as the 9th century, held among others by the von Garderode family; its first documented mention dates to the late 13th century. At the end of the 14th century it belonged to the Knights of Kalkum. The old castle was built between the 16th and 18th centuries for the von Velbrück family, and in the 18th century Nicolas de Pigage, also architect of Benrath Palace, designed the park. After passing by marriage to the Raitz von Frentz family around 1800, the old castle was demolished in the early 20th century except for the gate tower; Alhard von Burgsdorff then had the present building erected in 1912–1913 to plans by Max Wöhler.

The name Schloss Garath only came into use in the 20th century; before that the estate was usually called Haus Garath. The gate tower is the sole surviving part of the old castle, which stood from the 16th to the 18th century. In 2014 the building served as a remote country house for the board party in the film Stromberg – Der Film.

Schloss Garath stands in the Garath district of southern Düsseldorf, near where the Rietrather Bach and Galkhauser Bach join the Garather Mühlenbach. The grounds are privately owned and used commercially by around a dozen firms, so visits are limited to what can be seen from public paths. The gate tower of the old castle survives beside the 1912–1913 building.

The gate tower is the only surviving part of the old castle, which was otherwise demolished in the early 20th century. Alhard von Burgsdorff, grandson of the industrialist Gustav Poensgen, then had the present building erected on the same spot in 1912 and 1913 to plans by architect Max Wöhler. In 2014 the estate served as a remote country house setting for the board party in the film Stromberg.
