The track was produced by Steve Mac, who previously worked with the band on 'Glad You Came', 'All Time Low' and 'Lightning'.
'I Found You' will be released on November 4 ahead of The Wanted's third studio album.
Speaking of their new song, Nathan Sykes said: "We're doing a video for it in a couple of weeks as well in LA, which is really exciting. We are just trying to lock down all the ideas for it now."
Max George added: "We've been working on [our next album] for, like, the last six months, but it's still not ready yet. We're still working away on that and we've got plenty more travelling to do yet, so I'm not actually sure when the album is going to be ready."
Their new album will feature collaborations with LMFAO and Rita Ora.
The Wanted missed out on the 'Best New Artist' award to One Direction at last night's MTV Video Music Awards.
