"911" is a song by British virtual band Gorillaz & American hip-hop group D12 and features guest vocals from Specials' member Terry Hall. The song was recorded during 2001 in West London, after D12 were left stranded in England after the 9/11 terrorist attacks on New York City.

The song was recorded by Gorillaz and D12 in Damon Albarn's personal studio in West London. The track came about after 9/11 terrorist attacks on New York City. The track came about when Damon Albarn invited the band to his studio and played them an early demo of the track. Albarn had always wanted to experiment with Middle-Eastern music, and felt that this song would be perfect. D12 added additional production to the song, before laying down their verses. Terry Hall appears on the song as a vocal harmony with Albarn for the song's chorus. Albarn and Hall had previously spoken about collaborating together, however when Hall revealed that he had been taking singing lessons from a Middle-Eastern singer, it inspired Albarn to take the song in a different direction.

The video features the same visuals as "Clint Eastwood" and "19-2000", but with a different background. The track features D12 running towards the camera. Terry Hall does not appear in the music video.

Played live only twice, at the New York City Hammerstein Ballroom concert of Gorillaz Live in 2002. The song was also performed with Luton-based rap group, Phi Life Cypher, at the Isle of MTV Festival in Lisbon, Portugal.
