Cosmic Girls: Discography & Career Overview
A chronological look at Cosmic Girls's releases, lineup, and activity — grounded in verified release data.
Cosmic Girls debuted on February 25, 2016 under Starship Entertainment, introducing a ten-member lineup: Seola, Bona, Exy, Soobin, Luda, Dawon, Eunseo, Yeoreum, Dayoung, and Yeonjung. In the decade since, the group has assembled a catalog that spans mini-albums, one full-length studio release, and a succession of single albums — a body of work that reflects sustained activity across several distinct phases.
Debut & Early Releases
The group launched with the mini-album Would You Like? on the same date as their debut, February 25, 2016, led by the title track "Catch Me." A second mini-album, The Secret, followed in August 2016. Early 2017 brought From. WJSN with the title track "I Wish," before the group stepped up to their first full-length studio album, Happy Moment, in June 2017. Fronted by the title track "Happy," the studio album represented a structural shift from the shorter mini-album format that had defined their debut year.
Discography Arc
From 2018 onward, Cosmic Girls maintained a consistent release schedule built largely around the mini-album format. Dream Your Dream (February 2018, "Dreams Come True") and WJ Please? (September 2018, "Save Me, Save You") bracketed that year. In 2019, the group released three distinct projects: WJ Stay? in January with "La La Love," the summer release For the Summer in June with "Boogie Up," and As You Wish in November, which shared its name with its title track.
The 2020 releases shifted in character — Neverland arrived in June with "Butterfly," followed by the single album Hmph! in October. The group then released two projects in quick succession during the spring of 2021: the mini-album Unnatural in March and the single My Attitude in May, led by "Easy." Through 2022, Cosmic Girls moved exclusively to single albums, issuing Super Yuppers! in January and Sequence in July, the latter centered on "Last Sequence."
Recent Releases
Following the 2022 releases, Cosmic Girls returned to activity with Bloom Hour, a single album released on February 25, 2026 — a date that coincides precisely with the tenth anniversary of the group's debut. Led by the title track "Bloom Hour," the release marks the group's re-emergence under Starship Entertainment after a multi-year gap in output, bringing their active catalog to sixteen entries across just over a decade together.
