Letters to Father Jacob (Finnish: Postia pappi Jaakobille) is a 2009 Finnish drama film written and directed by Klaus Härö. Set in the early 1970s and based on a story by Jaana Makkonen, the film tells the story of Leila, a pardoned convict, who becomes an assistant to a blind priest, Jacob. The film depicts her transformation from a sceptic who grudgingly reads letters aloud to her benefactor into a caring savior of the pastor from his despair after the letters stop coming.

In 2022, the film was chosen as the "most touching Finnish film of the 21st century" in the Helsingin Sanomat readers' vote.
