Turning to Stone is a Canadian docudrama television film, which was broadcast by CBC Television in 1986. Directed by Eric Till and written by Judith Thompson, the film stars Nicky Guadagni as Allison Campbell, a woman who is sent to Ontario's Prison for Women after being set up by her boyfriend to smuggle drugs from Mexico to Canada without her knowledge.

The film was based on interviews with real women in prison, conducted by documentarian John Kastner during the creation of his documentary films The Parole Dance and The Lifer and the Lady. Many of the incidents depicted in the film were real occurrences which the prisoners had not felt comfortable or safe discussing openly on camera, but which Kastner felt were valuable illustrations of the importance of prison reform, so he chose to produce his first-ever scripted fiction film to dramatize them as a companion piece to his prison documentaries.

The cast also includes Anne Anglin, Jackie Richardson, Kim Renders, Maria Vacratsis and Shirley Douglas as fellow inmates in the prison, Bernard Behrens as Allison's father, and Paul Gross, Lubomir Mykytiuk and Barbara Budd in small supporting roles.

The film was broadcast by the CBC on February 25, 1986.
