Lee Jun-young, formerly known as Jun, is a South Korean singer, actor and former member of the boy groups U-KISS and UNB.

He debuted in June 2014 as U-KISS's rapper, vocalist and maknae with their 9th mini-album, Mono Scandal. The group had already debuted in 2008, but Global H Media decided to add him to the lineup after several auditions to replace member AJ, who was on hiatus.
