I Love You, Daddy is a 2017 American comedy-drama film written and directed by Louis C.K. and starring C.K., Chloë Grace Moretz, Rose Byrne, Charlie Day, Edie Falco, Pamela Adlon, Ebonee Noel, Helen Hunt, and John Malkovich. Co-producer Vernon Chatman co-wrote the story with C.K. It is C.K.'s third feature film as a director. He plays television writer and producer Glen Topher, who becomes disconcerted after his teenage daughter (Moretz) takes interest in a much older film director (Malkovich).

The film premiered at the 2017 Toronto International Film Festival on September 9, 2017. Initially scheduled to be released in the United States on November 17, 2017, by The Orchard, the film was dropped following sexual misconduct accusations made against C.K. a week prior to the intended debut. On December 8, 2017, it was reported that C.K. was purchasing the film's global distribution rights back from The Orchard.
