"Happiness in Slavery" is a song by American industrial rock band Nine Inch Nails from their extended play, Broken (1992).

The song takes its title and refrain from Jean Paulhan's preface to Pauline Réage's 1954 erotic novel Story of O.

The music video for "Happiness in Slavery", directed by Jon Reiss, was inspired by the 1899 novel The Torture Garden by French author Octave Mirbeau.
