The Palme d'Or is the highest prize awarded to the director of the Best Feature Film of the Official Competition at the Cannes Film Festival.
It was introduced in 1955 by the festival's organizing committee.
Previously, from 1939 to 1954, the festival's highest prize was the Grand Prix du Festival International du Film.
In 1964, the Palme d'Or was replaced again by the Grand Prix, before being reintroduced in 1975.
