Annie Blackburn, b. December 24, character in the Mark Frost and David Lynch television series, Twin Peaks, which aired over 29 episodes on ABC from 1990-91.

She is portrayed by American film actress Heather Graham and appears in the final 6 episodes of the series and briefly in the prequel feature film "Twin Peaks: Fire Walk with Me". She is a former Nun who hasn't decided if she wants to remain in the secular world, but is willing to see what it can offer her. Despite her lack of experience outside the Convent, she is not naive about everyday sorrows and transgressions. She can be seen as a mirror for Special Agent Dale Cooper. She seems to possess an intangible quality that he is drawn to, almost hypnotically. She ultimately begins to represent a dark and painful truth from his past. Subsequently, she is cast into Agent Cooper's urgent quest to elude/capture the progenitor of his increasingly nightmarish existence. In the final episode of the series she is trapped in the Black Lodge when Dale Cooper is possessed by the spirit of Bob. She appears to Laura Palmer in a dream bruised and bloodied to warn her but as the events are still to happen Laura does not understand the message.
