Pierre Georges Daix (24 May 1922 – 2 November 2014) was a French journalist, writer and art historian. He was a friend and biographer of Pablo Picasso.

As a young man, Daix was an ardent Stalinist. He joined the French Communist Party at the age of 17 in 1939 when the Communist Party was banned for supporting the German-Soviet pact. In July 1940, he created a student club, the Centre laïque des auberges de la jeunesse (Claj), which served as a legal screen for the clandestine Union of Communist Students.
