Super Junior (Korean: 슈퍼주니어; Syupeo Junieo), also known as simply SJ or SUJU, is a South Korean boy band. 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, Hangeng, Yesung, Kangin, Shindong, Sungmin, Eunhyuk, Siwon, Donghae, 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 by the same name. 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.

Super Junior remained the best-selling K-pop artist for four years in a row. Super Junior has earned 13 awards at the Mnet Asian Music Awards, 16 at the Golden Disk Awards, and are the second singing group to win Favorite Artist Korea at the 2008 MTV Asia Awards after jtL in 2003. In 2012, they were nominated for “Best Asian Act” in MTV Europe Music Awards. In 2015, they won the “International Artist” and “Best Fandom” in the Teen Choice Awards.
