I Can Do Bad All by Myself is a 2009 American romantic musical comedy-drama film which was released on September 11, 2009. The film was directed, produced, and written by Tyler Perry, who also makes an appearance in the film as his signature character Madea. The rest of the cast consists of Taraji P. Henson, Adam Rodriguez, Brian White, Mary J. Blige, Gladys Knight, and Marvin L. Winans. Although the film and play share the same title, the film is not an adaptation of Perry's play of the same name; the two works have different storylines as this film tells the story of an alcoholic lounge singer who is persuaded to take the custody of her niece and nephews by Madea after she catches them breaking into her house and their grandmother has gone missing. Both are named for a lyric in the Changing Faces song "G.H.E.T.T.O.U.T.". It is the fifth film in the Madea franchise.

Despite receiving generally mixed reviews from critics, I Can Do Bad All by Myself was a box office success, grossing $51.7 million worldwide against a $19 million budget.
