Teaching Mrs. Tingle is a 1999 American teen black comedy thriller film written and directed by Kevin Williamson in his directorial debut, and starring Helen Mirren, Katie Holmes, Marisa Coughlan, Barry Watson, and Jeffrey Tambor. It follows a trio of high school seniors who must prove their innocence to their vindictive history teacher, who accuses them of cheating on their final exams. Williamson wrote the script before his work on Scream and Dawson's Creek. Following the success of those projects, his script was picked up and production of the film proceeded.

Released in the United States on August 20, 1999, the film was originally titled Killing Mrs. Tingle and had a darker tone. It was delayed, re-edited and retitled due to the uproar over teen violence in films after the Columbine High School massacre. The film received mostly negative reviews from critics and was a box-office bomb.
