Union J are a British pop boy band from the United Kingdom. The group forms in 2011 under the name Triple J and begins as a trio made up of Josh Cuthbert, JJ Hamblett and Jaymi Hensley. George Shelley joins in 2012, after the group appears on the ninth series of The X Factor, where they finish fourth.

After the television series, Union J sign to RCA Records, a Sony Music subsidiary. Their debut single, “Carry You”, is released in 2013, followed by their self-titled first album later that year. That album reaches number six on the UK Albums Chart. In 2014 they leave RCA and sign with Epic Records. Their second album, You Got It All – The Album, also appears in 2014 and is preceded by the singles “Tonight (We Live Forever)” and “You Got It All”.

Line-up changes follow after their early success: Shelley leaves in 2016 and Casey Johnson replaces him, though Johnson leaves in 2017. The group later reforms in 2022 with the four original members and performs at the London Palladium, marking ten years since their first X Factor audition. Union J remain active.
