Mark Lee (이마크), born August 2, 1999 and known professionally as MARK (마크), is a Canadian performer of South Korean descent. MARK is the main rapper, main dancer, and sub-vocalist of K-Pop group NCT and its sub-units NCT U, NCT 127, and NCT DREAM—sub-unit in which he is also the leader and face of the group. Since 2019, MARK has also been part of SM Entertainment’s supergroup SuperM. Throughout his career, MARK has gained over 70 songwriting credits registered on Korea’s Music Copyright Association.
He debuted on April 8, 2016, as a member of NCT and NCT U with “일곱 번째 감각 (The 7th Sense).” On July 7, 2016, MARK went on to debut with NCT 127 through “소방차 (Fire Truck).” Later on, on August 24, 2016, MARK also debuted in NCT DREAM with the bubblegum pop song “Chewing Gum.”
From 2016 to 2018, MARK took part in the release of multiple official television soundtracks, such as “니 맘에 들어갈래 (What To Do)” with Henry Lau, and “Dream Me,” alongside Red Velvet’s JOY. Additionally, he participated in S.M. Station’s project song “Young & Free,” featuring EXO’s XIUMIN, and worked on his first solo song “두고가 (Drop),” which was performed with labelmate SEULGI of Red Velvet for the final of the hip-hop survival show High School Rapper.
In October of 2019, MARK was announced as a member of SuperM and debuted with the title track “Jopping.” While MARK initially left NCT DREAM at the end of 2018 due to its age-based graduation system, the system was abolished in 2020 and allowed him to rejoin the group with the song “무대로 (Déjà Vu; 舞代路).”
MARK’s first release as a soloist, “Child,” was the introduction to SM STATION’s NCT-focused project NCT LAB, and the third official solo release of any NCT member. The hip-hop song with rock influences was officially released on February 4, 2022. Just over a year later, his second solo release, “Golden Hour” was released on 7th of April, 2023 as part of the same NCT LAB project.
