Thallwitz is a municipality in the Leipzig district in Saxony, Germany.

The castle was built around 1580 by the Lords of Canitz in place of the medieval ancestral seat of those of Dallwitz.

At the end of the 17th century, the manor came to the chamberlain and chief equerry Christoph Siegmund von Holtzendorff, who had the Baroque garden laid out from 1699.

In 1882, the architect Arwed Roßbach added a Neo-Renaissance wing with a tower to the palace on behalf of Prince Heinrich XIV.

In 1945 the castle was expropriated; In 1992 the Free State of Saxony became the owner of Schloss Thallwitz.
