The Musée d'Art Moderne Grand-Duc Jean, or Mudam for short, is Luxembourg's museum of modern art. It is located on the grounds of Fort Thüngen (Dräi Eechelen) on the Kirchberg plateau in Luxembourg City.
The Mudam is managed by the Fondation Musée d'Art Moderne Grand-Duc Jean with substantial funding from the Luxembourg State; the Chairwoman of the Board of Directors is Grand Duchess Maria Teresa of Luxembourg.
The architect of the building, which opened on July 1, 2006, is Ieoh Ming Pei, which is why the museum is also popularly known as the "Pei-Musée". The museum bears the name of Grand Duke Jean, father of the current Grand Duke Henri.

The majority of the exhibits come from Luxembourg artists or from neighboring countries. There are currently around 230 works by over 100 artists, which are presented on three floors with around 3000 m² of exhibition space. Many of them are commissioned works that have been adapted to the space.
The museum showcases different genres of art, ranging from painting, drawing, photography, multimedia, fashion, design, graphics and sound to architecture.
Around 30 artists were involved in the Be the Artists' Guest project, in which they were able to integrate their works.

In the first year after opening, more than 115,000 visitors were counted, a record for a Luxembourg museum. The Mudam Boutique integrated into the building offers a wide selection of contemporary art media, postcards and gift items ranging from toys to designer pieces. The Mudam Café offers a variety of gluten-free vegetarian and vegan dishes.
Marie-Claude Beaud was succeeded by Enrico Lunghi from 2009 to 2017 and Suzanne Cotter from January 1, 2018. In January 2022, Cotter will return to her home country of Australia as Director of the Museum of Contemporary Art Sydney.
