"One Love" is the third single released by French DJ and record producer David Guetta from his fourth studio album of the same name. The single was released in the United Kingdom on 23 November 2009. It features guest vocals by Grammy Award-winning British singer Estelle. It was added to the BBC Radio 1 playlist the week of 28 October 2009.

David Balls of Digital Spy gave the song a positive review stating:

David Guetta must feel like le chat who got la crème. During 2009, the French knob-twiddler has notched up a pair of No. 1s ('When Love Takes Over', 'Sexy Bitch'), produced The Black Eyed Peas' record-breaking smash 'I Gotta Feeling', and teamed up with a glittering array of A-list stars for his One Love album. What's more, he hasn't run of out puff just yet. This time around, he's recruited our very own Estelle to help him pack out the dancefloor. His production's as clubby and anthemic as ever, but it's La Swaray who brings that extra bit of magic to 'One Love'. As with her 2005 Faithless collaboration 'Why Go?', her vocals ooze a melancholy optimism that dovetails perfectly with the heady beats. The result not only extends Guetta's winning streak, but also whets the appetite for Estelle LP#3 – in prog now.
