The Altes Museum (English: Old Museum) is a listed building on the Museum Island in the historic centre of Berlin, Germany. Built between 1825 and 1830 by order of King Frederick William III of Prussia according to plans by Karl Friedrich Schinkel, it is considered a major work of German Neoclassical architecture. It is surrounded by the Berlin Cathedral to the east, the Berlin Palace to the south and the Zeughaus to the west. Currently, the Altes Museum houses the Antikensammlung and parts of the Münzkabinett. As part of the Museum Island complex, the Altes Museum was listed as a UNESCO World Heritage Site in 1999, in recognition of its testimony to the development of the museum as a social and architectural phenomenon.

The building was also used in the newest Hunger Games movie The Hunger Games: The Ballad of Songbirds & Snakes for the exterior shots of the Academy, although slightly modified.
