"Heatwave" is a single from British grime artist Wiley, featuring vocals from Ms D – known for singing on the Chipmunk song "Oopsy Daisy".

It was released as the lead single from his ninth studio album The Ascent on 27 July 2012 for digital download in the United Kingdom.

It was written by Wiley, Dayo Olatunji and produced by Rymez, who is unofficially credited as a featured artist.

[1] Lewis Corner of Digital Spy gave the song a neutral review, calling it "a suitably cool summer jam, but if Wiley really wants to make an impact like his peers, he's going to have to dial the temperature up just a little bit higher yet.

[3][4] As predicted, the song entered the UK Singles Chart on 5 August 2012 at number 1, spending two weeks there (holding off "We'll Be Coming Back" by Calvin Harris and Example).
