The National Gallery in Berlin, Germany, is a museum for art of the 19th, 20th and 21st centuries. It is part of the Berlin State Museums. From the Alte Nationalgalerie, which was built for it and opened in 1876, its exhibition space has expanded to include five other locations. The museums are part of the Berlin State Museums, owned by the Prussian Cultural Heritage Foundation.

The Alte Nationalgalerie is a listed building on the Museum Island in the historic centre of Berlin, Germany. The gallery was built from 1862 to 1876 by the order of King Frederick William IV of Prussia according to plans by Friedrich August Stüler and Johann Heinrich Strack in Neoclassical and Renaissance Revival styles. The building's outside stair features a memorial to Frederick William IV. Currently, the Alte Nationalgalerie is home to paintings and sculptures of the 19th century and hosts a variety of tourist buses daily. As part of the Museum Island complex, the gallery was inscribed on the UNESCO World Heritage List in 1999 for its outstanding architecture and its testimony to the development of museums and galleries as a cultural phenomenon in the late 19th century.
