"In2" is the debut single by English R&B trio WSTRN. It was released on 6 November 2015 by Atlantic Records. The song peaked at number four on the UK Singles Chart, having initially reached number 60 based on streams alone.

The song was originally accompanied by a low-budget video of a West London block party directed by Morgan Keyz, and uploaded onto the Link Up TV YouTube channel. It was credited as Akelle Charles featuring Haile and Louis Rei, and was due to be released as the first single from the trio's EP, Western Union. However, the three artists adopted the collective name WSTRN following the song's popularity, and re-branded the song with a new video following its signing to Atlantic Records.

On 30 October, "In2" debuted at number 85 in the top 100 of the UK Singles Chart, and climbed to number 60 on 6 November, the day of its digital download release. For these two weeks, it charted on streams alone. Upon its digital release, the song entered the top 40 and peaked at number four, behind by Fleur East, Justin Bieber and Adele.
