Ludwigsburg Palace (German: Schloss Ludwigsburg) is a historical building in the city of Ludwigsburg (12 km north of Stuttgart's city centre), Germany. It is one of the country's largest Baroque palaces and features an enormous garden in that style.

From the 18th century to 1918 it was the principal royal palace of the dukedom that became in 1806 the Kingdom of Württemberg.

The foundation stone was laid on May 17, 1704 under Duke Eberhard Ludwig of Württemberg (reigning monarch from 1693 to 1733). One year later, the site was named "Ludwigsburg" (in English: "Ludwig's castle"). Begun as a hunting lodge, the project became much more complex and gained momentum over the years.

On August 17, 1709, the duke established the city of Ludwigsburg directly next to his palace, copying the proximity of Versailles to Paris. Previously, the royal palace was the cramped and outdated Old Castle (Altes Schloss) in the heart of Stuttgart. In 1718, Ludwigsburg temporarily became capital and sole residence of the dukes of Württemberg.
