Alias Jimmy Valentine is a 1928 American crime drama film directed by Jack Conway and starring William Haines, Leila Hyams, Lionel Barrymore, and Karl Dane. The film is based on the 1903 O. Henry story "A Retrieved Reformation", which was turned into the 1910 play Alias Jimmy Valentine by Paul Armstrong. The play toured in travelling production companies making it extremely popular. It was revived on Broadway in 1921. Two previous film adaptations had been produced at the old Metro Studios. A 1915 film version was directed by Maurice Tourneur and a 1920 version starring Bert Lytell was directed by Edmund Mortimer and Arthur Ripley.

Released on November 15, 1928, the film was Metro-Goldwyn-Mayer's first partially talking film. It was completed as a silent film before Irving Thalberg sent back Lionel Barrymore and William Haines to repeat their performances for the last two reels with sound.The film was shot in the middle of the night to avoid ambient noise infiltrating the soundtrack. Haines described the discomfort of working with sound: "You are confined to working quarters... that are almost airtight. You can hardly breathe, and in the hot weather it's like working in a boiler room... The sweat rolled off me until I could hardly stand it, and once I nearly felt like fainting".
