Kunstmuseum Heidenheim, Art museum in Heidenheim an der Brenz, Germany.

Kunstmuseum Heidenheim occupies the former Volksbad, a public bath built in 1903–1904 to plans by Philipp Jakob Manz in Jugendstil forms with Renaissance borrowings. The museum uses about 1,000 m²: contemporary art and 20th-century works in the Hugo Rupf hall upstairs (400 m²), and the former swimming pool, converted in 2001 into the Hermann Voith Galerie (330 m²) for Picasso posters and prints.

The building dates from 1904 when it served as the city's public swimming bath before being transformed into an art museum in 1989. This conversion allowed the historic structure to become a venue for displaying modern artworks.

The museum holds an important collection of Picasso posters that explore themes of peace, mythology, and bullfighting through visual imagery. These works allow visitors to see how the artist engaged with both social concerns and personal interests across different periods of his career.

The museum occupies the former Volksbad, so the entrance and galleries are reached through the old bathhouse building; the Picasso posters and prints are shown in the Hermann Voith Galerie, installed in the former swimming pool on 330 m². Temporary exhibitions occupy the upper floor and, since 2013, two small additional rooms. The sources give no opening hours or wheelchair information, so check these directly with the museum before visiting.

Two foundations support the museum's operations, the Hugo Rupf Foundation and the Hermann-Voith Foundation, ensuring stable funding for its programs. This backing allows the museum to maintain a steady schedule of exhibitions and events.
