Dau al Set (Catalan for "the seventh face of the die") was a highly influential Catalan avant-garde art and literary group formed in Barcelona in 1948. Emerging in the repressive cultural landscape of post-Civil War Francoist Spain, it is considered the first major artistic and intellectual movement to challenge the Francoist regime's conservative aesthetic.

The group, which included figures like the poet Joan Brossa, the philosopher Arnau Puig, and painters Antoni Tàpies and Joan Ponç, published an influential magazine under the same name. The name itself reflects their disruptive spirit, symbolizing a break from logic and a venture into the impossible. Drawing heavily from the influences of Dadaism and Surrealism , Dau al Set experimented with the worlds of the unconscious, magic, and the irrational, creating art filled with dreamlike imagery, fantastic creatures, and mystical symbols.

While rooted in Surrealism , the movement evolved, with many of its members moving toward the textural and abstract style of Art Informel , making Dau al Set a bridge in the development of post-war Spanish modern art.

The Dau al Set movement was founded by Joan Brossa in Barcelona in (1948), after World War II and the Spanish Civil War. The movement was centered around the magazine of the same name, which started publishing content in 1948 until 1951. Other key figures of the movement included Arnau Puig, Joan Ponç, Antoni Tàpies, Modest Cuixart and Joan-Josep Tharrats. The Dau al Set played an important role in Spanish post-war era art, as they explored new cultural and philosophical alternatives and aimed to positivize Catalan society during the first dark years of Francisco Franco's regime in Spain. The movement ended in 1956 due to the unstable situation of the main group behind it.

The Dau al Set magazine was founded by Joan-Josep Tharrats and it started being published along with the beginning of the art movement in 1948. It was a continuation of former magazine Algol , which was founded by the same group of people. Originally, the magazine was of Dadaist ideology, and the authors expressed their philosophical beliefs, such as being indifferent to society. Its ideology soon evolved into existentionalism and surrealism. The magazine especialized in various fields, such as philosophy, poetry and art. The Museum of Modern Art of New York City classified this magazine as one of the best twenty Avant-garde magazines of the 20th century.
