Changeling is a 2008 American crime drama film, written by J. Michael Straczynski and directed, co-produced and scored by Clint Eastwood, that explores child endangerment, female disempowerment, political corruption, mistreatment of mental health patients, and the repercussions of violence. Based partly on real-life events – the 1928 "Wineville Chicken Coop" kidnapping and murder case in Los Angeles, California – the film stars Angelina Jolie as a woman supposedly reunited with a boy she immediately realizes is not her missing son. When, however, she tries to demonstrate this to the police and city authorities, she is vilified as delusional and an unfit mother.

A changeling is a figure in West European folklore.
