The Berlin Biennale (full name: Berlin Biennale für zeitgenössische Kunst, Berlin Biennale for Contemporary Art) is a contemporary art exhibition which has been held at various locations in Berlin, Germany, every two to three years since 1998. The curator or curators choose the artists who will participate. After the event became established, annual themes were introduced. The Biennale is now underwritten by the German government through the Kulturstiftung des Bundes (Federal Culture Foundation), and is the second most important contemporary arts event in the country, after documenta.
