Pope Joan is a 1972 British historical drama film based on the story of Pope Joan. Even though modern consensus generally considers Pope Joan to be legendary, in the film her existence is treated as fact.

Pope Joan was, according to legend, a woman who reigned as pope for two years during the Middle Ages. Her story first appeared in chronicles in the 13th century and subsequently spread throughout Europe. The story was widely believed for centuries, but most modern scholars regard it as fictional.
