SM Rookies (Korean: 에스엠루키즈, stylized as SMROOKIES) is a pre-debut training team created by South Korean entertainment agency SM Entertainment in 2013, composed of trainees who have yet to join an idol group. From 2013 to 2018, the team officially introduced 30 members, with 24 of them later debuting in the groups Red Velvet (4), NCT and its first four subunits (19), and Aespa (1). After having been informally discontinued by the end of 2018, SM Rookies was revived by SM Entertainment in July 2022 with the introduction of three new trainees.
