Super Junior (Korean: 슈퍼주니어; Syupeo Junieo) is a South Korean pop group. Formed in 2005 by producer Lee Soo-man of S.M. Entertainment, the group comprised a total of thirteen members at its peak. Super Junior originally debuted with twelve members, consisting of leader Leeteuk, Heechul, Hankyung, Yesung, Kangin, Shindong, Sungmin, Eunhyuk, Donghae, Siwon, Ryeowook and Kibum. Kyuhyun joined the group in 2006.

Super Junior launched into international recognition following the release of their best-selling single "Sorry, Sorry" in 2009, the title song of their most critically successful album Sorry, Sorry. Over the years, they have been divided into smaller groups, simultaneously targeting different music industries and audiences. Largely due to Super Junior's success as entertainers, other Korean entertainment managements began to train their music groups in other areas of entertainment, such as acting and hosting.
