The Hungarian National Gallery, was established in 1957 as the national art museum. It is located in Buda Castle in Budapest, Hungary. Its collections cover Hungarian art in all genres, including the works of many nineteenth- and twentieth-century Hungarian artists who worked in Paris and other locations in the West. The primary museum for international art in Budapest is the Museum of Fine Arts.

Buda Castle is the historical castle and palace complex of the Hungarian Kings in Budapest. It was first completed in 1265, although the massive Baroque palace today occupying most of the site was built between 1749 and 1769. The complex in the past was referred to as either the Royal Palace or the Royal Castle. The castle now houses the Hungarian National Gallery and the Budapest Historical Museum.
