Lucky Boy is a 1929 American sound part-talkie musical comedy-drama film directed by Norman Taurog and Charles C. Wilson, most notable for starring George Jessel in his first known surviving feature picture. In addition to sequences with audible dialogue or talking sequences, the film features a synchronized musical score, singing and sound effects along with English intertitles. The sound was recorded using the Tiffany-Tone system using RCA Photophone equipment. The film's plot bore strong similarities to that of the hit 1927 film The Jazz Singer, which had originally been intended to star Jessel (the star of The Jazz Singer stage production) before Al Jolson took over the role.

Due to being a film published in 1929, it entered the public domain on January 1, 2025.
