NCT Dream is the third sub-unit of South Korean boy group NCT. The group was meant to follow an admission-graduation system, where members graduate from the unit after reaching the Korean age of 20 (19 internationally), however the system was removed in 2020.

The group debuted on August 25, 2016, with the single "Chewing Gum" along with the seven members: Mark, Renjun, Jeno, Haechan, Jaemin, Chenle, and Jisung. Mark graduated from the group on December 31, 2018, however following the termination of the admission-graduation system, he returned to the lineup in late 2020. In April 2026, he announced his departure from NCT and SM Entertainment.
