Dragon House (German Drachenhaus) is a historical building in Potsdam, Germany, built by King Frederick the Great of Prussia on the southern slope of the Klausberg, which borders the northern edge of Sanssouci Park.

It was constructed between 1770 and 1772 in the prevailing Chinoiserie taste of the time, designed to imitate a Chinese pagoda.

These architectural reference books were given to Frederick by the author, who had created for Augusta, Princess of Wales a large garden at Kew (near London), in which there still stands Chambers's many-tiered tapering Great Pagoda, completed in 1762.

The Dragon House at Sanssouci was built on an octagonal plan, with four floors not only to be decorative but also as living quarters for the wine-growers who worked on the neighbouring Weinberg.

Over the years, because of its inhabitation, an additional room, a laundry and three stables have extended the two rooms—a kitchen and an entrance hall—of the structure.
