Cure (キュア, Kyua) is a 1997 Japanese neo-noir psychological horror film

written and directed by Kiyoshi Kurosawa, starring Kōji Yakusho, Masato Hagiwara, Tsuyoshi Ujiki and Anna Nakagawa. The story follows a detective investigating a string of gruesome murders where an X is carved into the neck of each victim, and the murderer is found near the victim of each case and remembers the crime but does not know why they did it. The film is Kurosawa and Yakusho's first collaboration.

Originally entitled Evangelist (伝道師, Dendoushi), the film's name was changed due to the Tokyo subway sarin attack perpetrated by Aum Shinrikyo that happened while the film was in production. To avoid suggesting a religious cult connection to the crimes in the story, it was retitled Cure at the suggestion of a Daiei Film producer.

The film was released by Shochiku-Fuji Company on December 27, 1997. It received widespread positive reviews from critics, and is considered a progenitor of the explosion of Japanese horror media in the late 1990s and early 2000s, preceding other releases like Hideo Nakata's Ring and Takashi Shimizu's Ju-On.
