The Heartbreak Kid is a 1972 American romantic black comedy film directed by Elaine May and written by Neil Simon, starring Charles Grodin, Cybill Shepherd, Jeannie Berlin, Audra Lindley, Eddie Albert, and Doris Roberts. It is based on the short story "A Change of Plan", written by Bruce Jay Friedman and first published in Esquire in 1966.

In the film, a self-absorbed salesman (Grodin) marries his girlfriend (Berlin) after a short courtship. During his honeymoon, the salesman increasingly tires of his bride, finding that her earlier habits during courtship now irritate and repel him. Before the end of the honeymoon the salesman falls for a college-aged heiress (Shepherd) and impulsively courts her against her father's (Albert) wishes.

At the 45th Academy Awards, Berlin was nominated for Best Supporting Actress, and Albert for Best Supporting Actor. The Heartbreak Kid was ranked number 91 on AFI's 100 Years... 100 Laughs, a list of the funniest American films ever made, and was remade in 2007.
