"Bounce" is a song by Scottish DJ Calvin Harris. The song features American singer Kelis and is a move away from Harris singing, concentrating more on production. It was released on 12 June 2011 as the first single from Harris' third studio album, 18 Months (2012).

In November 2010, Harris claimed that he would no longer be singing on his tracks. He said, "I've stopped the live shows. I'm going to focus more on production and DJing and zero per cent of my time will go on singing. I'll do tracks with people who can sing well – proper artists, proper performers. I can focus on what I'm much better at, which is making music. I'm just not cut out for that role. I kind of fell into it a few years ago – the live show had to happen, I had to be the frontman because I was doing the vocals on the songs. It went all right. I spent a few years trying to get it really properly good, but it dawned on me it wasn't going to get much better. I've taken the singing thing as far as I can."

"Bounce" marked Harris' first single on which he did not provide the vocals. The song premiered on Annie Mac's show on BBC Radio 1 on 29 April 2011.

After the release of "Bounce", Harris released his follow-up single, "Feel So Close", and despite saying he would not be providing the vocals on his tracks, he returned to singing on the song.

"Bounce" has received generally positive reviews from contemporary critics. Lewis Corner from Digital Spy noted the successful transition of Harris' lack of vocals for the song saying "Kelis purrs over a midi-fied melody reminiscent of a classic Game Boy, before Harris takes the reins on the vocal-less chorus complete with bang-on-trend squiggly synths and head-bopping beats". Michael Cragg from The Guardian noted the club effect of the track saying "Opening with a pinging keyboard riff and Kelis intoning 'bounce', it soon morphs into a hands-in-the-air-ideally-holding-a-glow-stick dance monster, with Kelis's effortless cool keeping it's just the right side of parody." Sarah Deen from Metro noted the "hands-in-the-air chorus" but added "a marked improvement from his first single 'Merrymaking at My Place' but it's no 'I'm Not Alone'."
