"I'm a Slave 4 U" is the first single from pop singer Britney Spears released from the album Britney during the third quarter of 2001.

It is often considered a developmental milestone in Spears' career because of the single's steamy music video, somewhat raunchy lyrics and slight urban origins. The single is probably most well-known for the aforementioned video, which more fully redefined the then 19-year-old's controversial public image from the virginal Christian "girl next door" to a woman cashing in on her body, an image as controversial as the former.
