VIXX (Korean: 빅스 pronounced "vicks"; acronym for Voice, Visual, Value in Excelsis) is a six-member South Korean boy group, formed by Jellyfish Entertainment in 2012. All members participated in Mnet's survival reality show MyDOL and were selected via an elimination system through viewer votes. Originally, the group name was supposed to be VIX according to viewer's votes but it was changed to VIXX to make it visually pleasing. VIXX consists of N, Leo, Ken, Ravi, Hongbin and Hyuk. They are predominantly known as a concept or performance group whose music, lyrics, choreography, and overall stage performances are crafted together to tell a story or concept.

Before their official debut, the original VIXX members were 6 out of 10 contestants featured in the Mnet survival reality show MyDOL. Pre-debut, the members made several guest appearances in the music videos of fellow artists under Jellyfish Entertainment. N, Leo, Hongbin and Ravi were featured in Brian Joo "Let This Die" music videos. N, Leo, and Ravi were also featured in Seo in Guk's "Shake It Up". Hongbin was featured in Seo in Guk's "Tease Me".
