No Sleep Tonight is a song by British post-hardcore band Enter Shikari, taken from their second studio album, Common Dreads. The song was released as a single on 31 July 2009.

The song was produced by Andy Gray and was at Arreton Manor in the Isle of Wight. Lead Singer Rou Reynolds explained to Kerrang!: "This song is about conscience and how more and more oil companies are simply concerned with short-term profit and will pay scientists to speak out about climate change."

The music video was released in early July 2009, on TV and can be seen on Enter Shikari's YouTube official account.

It was directed by Shane Davey (who also directed the video for the band's last single Juggernauts) and features many of the band's fans. It follows the story of a man who accidentally knocks into lead singer Rou Reynolds as he's on the phone, comes home from work, followed by Rou and is then continuously told "You're not getting any sleep tonight". We the audience get to see his failing marriage end due to his arrogant and loveless ways.
