K-pop continues to grow in popularity around the world, with extremely talented and successful boy and girl bands in the genre. While some K-pop groups like BLACKPINK and Aespa only have four members in their roster, some groups have a large number of members, with some having as many as 23 members.

With so many singers, dancers, rappers, visuals, and more vying to become idols, K-pop groups stand out for categorizing their members into where they shine brightest. Regardless of the number of members in a group, they always seem to deliver bright and energetic performances.

From the 23 members of NCT, to the 13 members of the famous group Seventeen, here are 10 K-pop groups with the most members.


Neo Culture Technology, popularly known as NCT, is a K-pop boy group formed under the highly sought-after agency SM Entertainment. The group debuted in 2016 with 15 members and was divided into three sub-units, namely: NCT127, NCT DREAM and the non-fixed unit, NCT U. The age of the members ranges from late teens to mid-twenties. . If 15 weren’t enough, the group continues to grow and currently sits at 23 magnanimous members. Also, a new sub-unit was formed called WAYV, although it was promoted mainly in China. Aiming to carry out an original plan of building unlimited members, it looks like NCT could continue to reign at the top of the groups with the most members as they plan to add more idols in the coming years. .


Apeace was a boy group that debuted in 2010, boasting a massive 21 members under the initial nickname “Double B 21”. The group was formed by Golden Goose Entertainment and was once considered the K-pop group with the most members at the time.

Over the years, the group’s members have grown from 21 to 15, and in 2015, only 12 members remained. The group had three subunits: Lapis5, Onyx5, and Jade5. In 2021, the group’s Japanese agency announced that Apeace had officially disbanded.

Dubbed the “King of Hallyu Wave” for contributing greatly to the mainstream popularity of K-pop music, Super Junior is a boy group that debuted in 2005 under SM Entertainment. The group officially debuted on the scene with 12 members before adding a 13th member a year later. Eventually, Super Junior would drop three members, rounding up the member count to 10.

Launched in 2015 under Pledis Entertainment, the group consists of 13 members and has three tagged subgroups: Hip-hop Team, Vocal Team, and Performance Team.
