East 17 (later re-grouped as E-17) are an English pop boy band founded in 1992.

The group name came from the postcode for Walthamstow, an area of London between the old East End and the Essex commuter belt. They achieved 18 Top 20 singles and four Top 10 albums, and were one of the famous acts along with Take That in the UK and some parts of the world during the early to mid 1990s. They occasionally blended rap and pop in songs such as "House of Love", "Steam" and "Let It Rain", attaining fame as a result of the main songwriter Tony Mortimer.
