DAU. Degeneration is a 2019 Russian film of the DAU project organised by Ilya Khrzhanovsky.

During the early stages of production, the film was marketed as a biopic about the life of the Nobel Prize-winning Soviet scientist Lev Landau. However, as production progressed, the concept of the film drastically evolved into an alternative Soviet history series. The character of Lev Landau as played by Teodor Currentzis appears only in the films DAU. Nora Mother, DAU. Katya Tanya, DAU. The Empire and DAU. Three Days.

The premiere in Paris on 25 January 2019 was in the form of a dozen feature films screened inside an extensive around-the-clock immersive installation. The film is one of Russia's largest and most controversial cinematic projects.

DAU. Degeneration premiered in the Berlinale Special program in 2020.
