Chocolates for Breakfast is a 1956 American novel written by Pamela Moore. Originally published in 1956 when Moore was eighteen years old, the novel gained notoriety from readers and critics for its frank depiction of teenage sexuality, and its discussion of the taboo topics of homosexuality and gender roles.^[1] The plot focuses on fifteen-year-old Courtney Farrell and her destructive upbringing between her father, a wealthy Manhattan publisher, and her mother, a faltering Hollywood actress.

Upon its release in 1956, the novel became an international sensation and was published in multiple languages,^[2] with many critics drawing comparisons to the 1954 French novel Bonjour Tristesse by Françoise Sagan.^[3] Chocolates for Breakfast went out of print in 1967, and was not reprinted in the United States until Harper Perennial re-released the novel in June 2013.^[4] This marks its first re-printing in North America in over forty-five years.
