A Page of Madness (狂った一頁, Kurutta Ichipēji) is a 1926 Japanese silent experimental horror film directed by Teinosuke Kinugasa. Lost for 45 years until it was rediscovered by Kinugasa in his storehouse in 1971, the film is the product of an avant-garde group of artists in Japan known as the Shinkankakuha (or School of New Perceptions) who tried to overcome naturalistic representation. The film is set in a mental institution in contemporary Japan.

Yasunari Kawabata, who won the Nobel Prize for Literature in 1968, was credited on the film with the original story. He is often cited as the screenwriter, and a version of the scenario is printed in his complete works, but the scenario is now considered a collaboration between him, Kinugasa, Banko Sawada, and Minoru Inuzuka. Eiji Tsuburaya is credited as an assistant cameraman.
