"I Want You Back" is a song by Australian rock group Hoodoo Gurus, released in March 1984 as the fourth and final single from their debut album Stoneage Romeos.

The 7" single and video clip version of the song is an edit that removes the second half of the double verse usually heard before the first chorus.

In an interview with Fred Mills of Harp magazine in January 2007, Faulkner revealed that the song was written not about a former lover but about the split with Radalj "Basically, when Rod Radalj left the Gurus he was very dismissive of us, trying to move on and kind of burn everything behind him: ‘Oh, it’s not worth staying in that band.

They’re terrible!’ So I basically turned that emotion around: ‘Here’s this guy who ditched us and he’s acting like the spurned lover!’ It was me saying, 'You'll regret it.
