Lady Behave! is a 1937 American film directed by Lloyd Corrigan. The sophisticated comedy was released by Republic Pictures.
The film began with the title The Lady Misbehaves but Production Code Administration (PCA) director Joseph Breen strongly disapproved of the film's premise of "dealing with so serious a subject as a bigamous marriage, where the treatment is set for comedy." The Hays Office told Republic Pictures that in these times ladies do not misbehave; the dropping of "mis" would still give the desired undesirable impression. The PCA approved the film when several changes were made to the script and the title was changed.
