Lee Hyuk-jae (hangul: 이혁재; hanja: 李赫宰; born April 4, 1986), better known by his stage name Eunhyuk, is a South Korean singer-songwriter, dancer and actor. He is a member of the K-pop boy band Super Junior and their subgroups, Super Junior-T and Super Junior-H. In 2011, he joined Super Junior's Mandopop subgroup, Super Junior-M and the duo Donghae & Eunhyuk; active in China and Japan respectively.
Eunhyuk was born Lee Hyuk-jae in Goyang, South Korea. Raised in a family that struggled financially, he was interested in street performing as a child. Inspired by the likes of H.O.T's, Jang Woo-hyuk, Michael Jackson and singer-dancer Yoo Seung-jun, Eunhyuk trained himself at a young age. In elementary school he started a dance crew, 'SRD', which stood for Song Rap and Dance. The group consisted of him and his childhood friends Kim Junsu, Hwang Tae Jun, and Choi Min Seok. The crew's popularity prospered in their hometown; and when SRD appeared in a local newspaper, it was then that Eunhyuk cemented his dream to become a singer/performer.
