"911" is a duet between Haitian rapper Wyclef Jean and American soul music singer Mary J. Blige.

It was released on 5 September 2000 as the third single from Jean's second studio album, The Ecleftic: 2 Sides II a Book (2000), and was later included on Blige's compilation Reflections (A Retrospective) (2006).

The relationship is apparently under external pressures, as Jean sings "messing around with you is gonna get (the man) life", and later reflecting "it's worth the sacrifice".

It was also a top-10 hit in Denmark, Finland, Ireland, the Netherlands, Switzerland, and the United Kingdom.
