The Hendrik Christian Andersen Museum in Rome is a house museum that is part of the State Museums Directorate of the City of Rome (Mibact).

The Museum houses the works of the sculptor and painter Hendrik C. Andersen , born in Bergen, Norway on 17 April 1872 and a naturalized American, having emigrated with his family to Newport (Rhode Island) as a child.

The renovation and restoration works of the Andersen Museum , financed with funds derived from the Lotto game for the year 1998, made its opening to the public possible, which took place on 19 December 1999. The "training journey" towards the Europa, settled in Rome where he lived for over forty years, starting in 1897. Upon his death, on 19 December 1940, he left his studio-home in Via Mancini and its contents to the Italian State: works, furnishings , archive papers, photographic material, books.

The collection of works is made up of over two hundred sculptures , of which around forty are large in plaster and bronze; over two hundred paintings; over three hundred graphic works.

The Andersen Museum collection stands out for its exceptional nature, being almost entirely centered around the utopian idea of a great "World City", destined to be the international headquarters of a perennial laboratory of ideas in the fields of arts, sciences, philosophical and religious thought. In 1913 Andersen, together with the French architect Ernest Hébrard, dedicated a powerful illustrated volume (Creation of a World Center of Communication) to this project and its diffusion which, starting from the urban planning conceptions of ancient civilisations, was to indicate the arrival at new and modern "City".

Only after the death in 1978 of Lucia Andersen (adopted in 1919 by the artist's mother, and therefore usufructuary of the legacy), was the National Gallery of Modern Art entrusted with the protection of the collections and the building, which had been subject to restrictions since 1975 pursuant to law no. 1089/39. The renovation and restoration works of the Museum, financed with funds derived from the Lotto game for the year 1998, made its opening to the public possible, which took place on 19 December 1999.

Numerous exhibitions are also organized in the Hendrik Christian Andersen Museum .
