When the Bough Breaks is a 1947 film directed by Lawrence Huntington and starring Patricia Roc and Rosamund John. It is an adaptation of an original storyline by Herbert Victor on adoption and the competing ties of one child's birth and foster family.

Patricia Roc was an English film actress, popular in the Gainsborough melodramas such as Madonna of the Seven Moons (1945) and The Wicked Lady (1945), though she only made one film in Hollywood, Canyon Passage (1946). She also appeared in Millions Like Us (1943), Jassy (1945), The Brothers (1947) and When the Bough Breaks (1947).
