Saint Clare is a 2024 American thriller film written by Mitzi Peirone and Guinevere Turner, directed by Peirone and starring Bella Thorne, Rebecca De Mornay, Ryan Phillippe, and Frank Whaley. It is based on the novel Clare at 16 by Don Roff.
To the world, Clare Bleecker appears to be a normal student, an animal lover and devout vegan living with her grandmother. But like the small town she lives in, Clare is more than she appears to be. Underneath her reserved appearance lives a sociopath with dissociative identity disorderâÂÂa serial killer.
In January 2019, Deadline reported that Madelaine Petsch would play the titular character and also serve as an executive producer on the film. However, in May 2022, Bella Thorne was announced to replace Petsch in the lead role after she signed on to star in The Strangers Trilogy films, causing her to drop out of the project.

In August 2022, it was announced that the film was in post-production and had been re-titled to Saint Clare.
On June 4, 2025, Quiver Distribution acquired the film distribution rights, and released the film in select theaters and on demand on July 18, 2025.
