The Sonning Prize (Danish: "Sonningprisen") is awarded biennially for outstanding contributions to European culture. A committee headed by the rector of the University of Copenhagen decides among candidates proposed by European universities. The prize amounts to 1 mio DKK (~135,000 €). The prize award ceremony is held on April 19 (Sonning's birthday) at the University of Copenhagen. The prize was established by will of the Danish editor and author Carl Johan Sonning (1879–1937). It was first awarded in 1950 and subsequently every second year from 1959.
