"Goin' Crazy" is a song by Dizzee Rascal, featuring vocals from English singer-songwriter Robbie Williams. The song was written and produced by Tim Anderson and Jamin "J-Man" Wilcox, with additional production by Nick Cage, and co-written by Dizzee Rascal. The song was released on 16 June 2013 as a digital download in the United Kingdom as the lead single from his upcoming fifth studio album The Fifth (2013). Dizzee originally had Example sing the chorus instead of Williams, but he felt it didn't work out, paving the way for Williams to sing it.

The music video for the song was uploaded to YouTube on 10 May 2013 at a length of three minutes and forty seconds. The video shows Robbie Williams driving around London in modified mobility scooters surrounded by an entourage of grannies before meeting up with Dizzee as they carry on with their journey. The video also features a cast of iconic lookalikes including Roy Orbison, Elvis Presley and John Lennon. The video also features a cameo appearance from Gordon Smart the showbiz columnist in The Sun.

On 24 May 2013 Dizzee Rascal surprised fans at Radio 1's Big Weekend in Ebrington Square, Derry, County Londonderry, Northern Ireland by performing the song live with a special guest performance from Robbie Williams.

Robert Copsey of Digital Spy gave the song a mixed review stating:

"In short, the answer is an unfortunate yes. That's not to say the pair themselves aren't surprisingly well-matched - each craving the other's self-assurance and youthful charm - but musically, the effect is far less harmonious. While Rascal raps about dating models and scoring drugs in clubs, Williams admits: "I believe I'm going crazy/ I believe I'm losing my mind," the result a Frankensteinian blend of indie, grime and pop that never quite hits the spot." .
