Super Junior M is the third official sub-unit of South Korean boy band Super Junior, established during the first two weeks of April, 2008. They are the first international music group in the Chinese music industry to have members of both Chinese and Korean descent. The sub-group had five Super Junior members (Han Geng, Donghae, Siwon, Ryeowook and Kyuhyun), and two new members (Henry and Zhou Mi) in its original line-up.

With Han Geng's departure from Super Junior in 2009, the sub-group, despite not active, was left with only six members. In February 2011 they made a comeback with 太完美 (Perfection), and two Super Junior members were chosen as temporary members during its promotions: Sungmin and Eunhyuk. Read more on Last.fm.
