"Bad Girl" is a song by American singer and songwriter Madonna, recorded for her fifth studio album, Erotica (1992). The song was written by Madonna, Shep Pettibone and Anthony Shimkin, and produced by Madonna and Pettibone.

The music video for "Bad Girl" features Madonna playing the character "Louise Oriole" (Madonna's middle name is Louise and Oriole is a street she once lived on), a high-powered and successful but ultimately lonely Manhattan female executive who is a chain smoking alcoholic with a penchant for one-night stands with many different men. She behaves this way in order to try and deal with her depression and sadness over a relationship with someone she loves deeply, but ultimately has no future. Through her days, Louise gets distracted by cigarettes, cocktails, and random hook-ups, as lamented in the song's lyrics. Christopher Walken plays her guardian angel, who watches over her self-destructive activities.
