The Mánes Association of Fine Artists (Czech: Spolek výtvarných umělců Mánes or S.V.U.; commonly abbreviated as Manes) was an artists' association and exhibition society founded in 1887 in Prague and named after painter Josef Mánes.
The Manes was significant for its international exhibitions before and after World War I that encouraged interaction between Czech artists and the foreign avant-garde. It played an important role in the development of Czech Cubism and Rondocubism. Between 1928 and 1930, Manes built a complex with a restaurant, club, showroom and offices at the site of the Štítkovský Mill and water tower on the Vltava. The architect of the 1928 Manes pavilion was member Otakar Novotný .
The union was liquidated under the Communists and was revived after the Velvet Revolution in 1990. Its headquarters became the Diamond House in Prague, itself a landmark of cubist architecture.
Svaz výtvarných umělců Mánes ("Association of Fine Artists Mánes") was established in 1887 as a group of Bohemian artists in the Austrian-Hungarian Empire. Its forerunner was Škréta, spolek mladých českých výtvarníků v Mnichově ("Škréta, a Fellowship of Young Czech Artist in Munich"), an organization of Czech art students in Munich, an art center largely visited by Central and Eastern European art students. The name of this society came from seventeenth century Bohemian painter Karel Škréta. Formed in 1885 it became one of the largest communities of Czech students abroad. It had its own infrastructure and annual show. It had regular contact with the homeland and published a journal in two parts: Paleta & Špachtle ("Palette" and "Spatula"). This journal was circulated within the association only and all members had to contribute to it on weekly bases. Their focus was mainly on the German art scene. The group accepted other Slavic students as members.
