The Schleissheim Palace comprises three individual palaces in a grand baroque park in the village of Oberschleißheim, a suburb of Munich, Bavaria, Germany. The palace was a summer residence of the Bavarian rulers of the House of Wittelsbach.

The history of Schleissheim Palace started with a renaissance country house (1598) and hermitage founded by William V close to Dachau Palace. The central gate and clock tower between both courtyards both date back to the first building period. The inner courtyard is called Maximilianshof, the outer one Wilhelmshof. Under William's son Maximilian I the buildings were extended between 1617 and 1623 by Heinrich Schön and Hans Krumpper to form the so-called Old Palace. This plan is typologically similar to the castle of Laufzorn in Oberhaching begun by Maximilian's brother Albert the year before. There, too, a free staircase leads up to the first floor, which is used as a mansion. The building, which was designed in the style of Andrea Palladio in the late renaissance, was completed in 1623.

The rooms were decorated by Peter Candid. Maximilian's son and successor Ferdinand Maria died here in 1679. After heavy destruction in the Second World War the palace with its spacious buildings was reconstructed. Most of the stucco decoration of the chapel Wilhelmskapelle has been preserved. The Old Schleissheim Palace houses today two exhibitions, one on religious culture, the other the history of Prussia. The Grand Hall in the middle of the main building today serves as foyer for the museums.

The grand park is one of the rare preserved baroque gardens in Germany. Its structure with canals and bosquet area was arranged by Zuccalli. Dominique Girard, a pupil of Le Notre, constructed the grand parterre and the cascade until 1720. Water forms since the central element in the garden. The Grand Canal in the garden center and the ditch round of Lustheim island are part of the northern Munich channel system, a system of waterways that connected also to the complex of Nymphenburg Palace.

From the Old Palace, a line of sight goes south to the Frauenkirche in Munich, which is also the end point of another line of sight of the Fürstenried Palace. The northern side channel has finally Dachau Palace as target. In the Brunnhaus (well house), which was built in 1867 north of the Old Palace by Carl von Effner, the waterwheel and the pumps are still present, the fountains are, however, now powered by electric pumps.
