The Volpi Cup for Best Actress is an award presented by the Venice Film Festival. It is given by the festival jury in honor of an actress who has delivered an outstanding performance from the films in the competition slate. It is named in honor of Count Giuseppe Volpi di Misurata, the founder of the festival. The 1st ceremony was held in 1932, when Helen Hayes received the Volpi Cup for the title role in The Sin of Madelon Claudet (1931)—this was the only time that the award was chosen by public voting. From 1942 to 1945, the festival was suspended because of World War II. The student protests in May 1968 opened a period of institutional changes, with no prizes were awarded from 1969 to 1979.
