My Foolish Heart is a 1949 American romantic drama film directed by Mark Robson, starring Dana Andrews and Susan Hayward. It relates the story of a woman's reflections on the bad turns her life has taken.

Adapted from J. D. Salinger's 1948 short story "Uncle Wiggily in Connecticut", this remains the only authorized film adaptation of Salinger's work; the filmmakers' infidelity to his story was responsible for precluding any other film versions of other Salinger works, including The Catcher in the Rye. The film inspired the Danish story Mit dumme hjerte by Victor Skaarup.
