East 17 are an English pop boy band started by Tony Mortimer, Brian Harvey, John Hendy, and Terry Coldwell in 1991. As of 2020, the group consists of Coldwell, Robbie Craig and Joe Livermore. East 17 have undergone multiple lineup changes, with Coldwell remaining the only constant member.

The group has released 18 top-20 singles and four top-10 albums and was one of the UK's most popular boy bands during the early- to mid-1990s, aided by strong tabloid interest in their 'bad boy' image, compared to the clean-cut style of rivals Take That. Their style blended pop and hip hop in songs such as "House of Love" and "Let It Rain".

East 17 has sold over 18 million albums worldwide and according to the British Phonographic Industry (BPI), the group has been certified with sales of 1.8 million albums and 2.6 million singles in the UK. Their biggest hit, "Stay Another Day", was the UK Christmas number one in 1994.

The group continues today under the lineup of Terry Coldwell, Joe Livermore, and former Artful Dodger collaborator Robbie Craig.
