The 26th Cannes Film Festival was held from 10 to 25 May 1973. The Grand Prix du Festival International du Film went to Scarecrow by Jerry Schatzberg and The Hireling by Alan Bridges. At this festival two new non-competitive sections were added: 'Étude et documents' and 'Perspectives du Cinéma Français'.

The Palme d'Or is the highest prize awarded 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.
