The Pergamon Museum (German: Pergamonmuseum; pronounced [ˈpɛʁ.ɡa.mɔn.muˌzeː.ʊm] (listen)) is a listed building on the Museum Island in the historic centre of Berlin and part of the UNESCO World Heritage. It was built from 1910 to 1930 by order of German Emperor Wilhelm II according to plans by Alfred Messel and Ludwig Hoffmann in Stripped Classicism style. Currently, the Pergamon Museum is home to the Antikensammlung including the famous Pergamon Altar, the Vorderasiatisches Museum and the Museum für Islamische Kunst. Parts of the building are closed for renovation until 2025.

By the time the Kaiser-Friedrich-Museum on Museum Island (today the Bodemuseum) had opened in 1904, it was clear that the edifice was not large enough to host all of the art and archaeological treasures being excavated under German supervision. Excavations were underway in the areas of ancient Babylon, Uruk, Assur, Miletus, Priene and ancient Egypt, and objects from these sites could not be properly displayed within the existing German museum system. Wilhelm von Bode, director of the Kaiser-Friedrich-Museum, initiated plans to build a new museum nearby to accommodate ancient architecture, German post-antiquity art, and Middle Eastern and Islamic art.
