Voina (Russian: Война, IPA: [vɐjˈna] , lit. 'War') is a Russian street-art group known for their provocative and politically charged works of performance art. The group has had more than sixty members, including former and current students of the Rodchenko Moscow School of Photography, Moscow State University, and University of Tartu. However, the group does not cooperate with state or private institutions, and is not supported by any Russian curators or gallerists.
The activities of Voina have ranged from street protest, symbolic pranks in public places, and performance-art happenings, to vandalism and destruction of public property. More than a dozen criminal cases have been brought against the group. On 7 April 2011 the group was awarded the "Innovation" prize in the category "Work of Visual Art", established by the Russian Ministry of Culture.
