The Sprengel Museum is a museum in Hanover dedicated to modern and contemporary art. Inaugurated in 1979, the museum was born thanks to the donation of collectors Margit and Bernhard Sprengel, who in 1969 largely left their vast collection of modern art to the city of Hanover.

The collection includes notable groups of works by Max Ernst, Fernand Léger, Paul Klee, Pablo Picasso and Max Beckmann, Emil Nolde and Kurt Schwitters, among others. There are also important groups of artists such as Die Brücke and Der Blaue Reiter, as well as styles such as Cubism and Surrealism. Since about 1980, the museum's holdings have been expanded to include major art movements after 1945, including works by Andy Warhol, Alexander Calder, Ernst Marow, Gerhard Richter, and Sigmar Polke. Special features of the museum include the reconstruction of the legendary Merz building by Kurt Schwitters and the bright rooms of James Turrell. Niki de Saint Phalle, who became known for her sculptures, enriched the Sprengel Museum Hannover with her donation in 2000. With over 400 works, all the essential creative phases of the artist are represented, including assemblies, shots, sculptures and drawings. The museum's graphic collection includes works by Abraham David Christian, Lyonel Feininger, Joan Miró, TA Steinlen, Henri de Toulouse-Lautrec, Käthe Kollwitz and Ernst Barlach.

The Spectrum Photo Gallery was integrated into the Sprengel Museum and formed the basis of the museum's photographic and multimedia collection.
