Weeekly (위클리) is a South Korean girl group formed under Korean talent agency, IST Entertainment. The group consists of 6 members: Monday, Zoa, Lee Soojin, Park Soeun, Jihan, and Lee Jaehee.

During October 2018, IST Entertainment announced their next plans for a new girl group after 10 years, following Apink. Before their current name, “Weeekly,” the group was named “FAVE Girls” before the changes. Soon, it would be that they would debut as a seven-member group with their first “We” mini-album series, We are.

After Weeekly’s second EP, We can, on March 2021, they soon took a turn with the title track of their 3rd mini-album, “After School”. “After School” blew up as it gained 50 million in under a month, with their performance video also gaining 10 million views. The song peaked at No. 21 for US World Digital Song Sales on Billboard, and No. 155 for South Korean Gaon charts.

Two months after “After School,” they released their first alone-single, “텐션업 (7days Tension)”. Following up with the meaning of their group name, “Weeekly”. This is also similar to their number of members that they used to have, which is 7, and 7 is the amount of days that a full week consists of. Three months after their single, they then came back once again with their new “Play Game” series titled, Play Game: Holiday.

On June 1st, 2022, Shin Jiyoon left the group, leaving the group to continue to promote as a six-member group.
