DIA (; ; derived from DIAMOND and an acronym for Do It Amazing) is a South Korean female idol group created by MBK Entertainment. The ensemble originally comprised six members: Eunice, Jueun, Huihyeon, Yebin, Chaeyeon, and Eunchae. Their official debut occurred on September 14, 2015, with the lead track "Somehow" from their album Do It Amazing.

Seunghee exited the group in April 2016 to pursue a career in acting. Eunjin left in May 2018 citing health concerns, followed by Jenny in July 2019 for similar health-related reasons. Somyi departed in January 2022 after contract termination. By September 2022, the remaining members parted ways with PocketDol Studio upon contract expiration; the group is currently on hiatus as members engage in solo endeavors under various agencies.

2015: Do It Amazing

In February 2015, MBK Entertainment revealed intentions to form a new girl group, initially considering launching a survival reality show. On February 10, Kim Dani joined the lineup under the tentative title T-ara's Little Sister Girl Group. However, by June, MBK decided to cancel the survival program and instead finalized member selection internally. The confirmed roster featured Eunice, Huihyeon (formerly Cathy), Jenny, Yebin, Eunjin, and Chaeyeon. Shortly before debut, Seunghee was added to complete the group. DIA's debut album Do It Amazing was released on September 14, 2015.

2016: Member shifts, Happy Ending, Spell, and subunits

In March 2016, Eunchae (birth name Chaewon) became part of DIA, while Seunghee departed the following month. The group introduced their first mini-album, Happy Ending, on June 14, 2016, with "On the Road" as the title track.

September 2016 saw the release of their Harry Potter-inspired album Spell, spotlighting "Mr. Potter" as its lead single. Later that year, DIA divided into two subunits—BinChaenHyunSeuS ("A" team) and L.U.B ("B" team)—each issuing distinct tracks aimed at broadening their market appeal.

2017: Additions, YOLO, and Love Generation

On April 6, DIA unveiled a pre-release single titled "You Are My Flower", collaborating with trot vocalists Kim Yeon-ja and Hong Jin-young. Soon after, Jueun and Somyi joined the group, expanding its membership to nine individuals. Their reality series debuted on April 9 via Onstyle. DIA's second full-length album, YOLO, dropped on April 19 featuring fourteen songs led by "Will You Go Out with Me?". The record included tracks composed by members alongside collaborations with rapper DinDin and former I.O.I member Kim Chung-ha.

The group's third mini-album, Love Generation, was released on August 22 containing twelve tracks with "Can't Stop" as the main single. A repackaged version titled Present followed on October 12, adding four new songs including the lead "Good Night".

2018: Eunjin's Exit and the Release of Summer Ade

On May 7, 2018, Eunjin departed from the group citing health concerns. DIA announced on June 9 that they would be making a comeback scheduled for July 5, 2018. Originally intended for an April release with a song produced by Shinsadong Tiger, the comeback was delayed several times to maintain high standards. Ultimately, the group unveiled their fourth EP, Summer Ade, on August 9, 2018, with the lead single titled "Woo Woo". A landmark achievement followed on August 14 when DIA secured their first music show victory on SBS MTV's The Show.

2019–2020: Newtro, Jenny's Departure, and the Flower 4 Seasons Comeback

A comeback initially planned for November 7, 2018, featuring "Bo Peep Bo Peep 2.0" produced by Shinsadong Tiger was postponed. On February 20, MBK Entertainment confirmed DIA’s return with Shinsadong Tiger producing their first project as a seven-member lineup without Jenny, who was sidelined due to a knee injury. The group's fifth EP, Newtro, including the title track "Woowa", was released on March 19, 2019.

Jenny officially left the group on July 6, 2019, as announced by MBK Entertainment, due to persistent knee problems.

DIA’s sixth EP, Flower 4 Seasons, was confirmed on May 25, 2020, with a release date of June 10. This marked their inaugural project under PocketDol Studio. Promotions were conducted as a five-member formation without Chaeyeon and Somyi.

Although a comeback was announced for January 2021 on November 12, 2020, it ultimately did not take place.

2022: Somyi's Departure, Rooting for You, and Hiatus

Somyi officially ended her contract and exited DIA on January 9, 2022, as confirmed by PocketDol Studio.

On May 11, 2022, it was revealed that DIA would release their final album in August before their contracts expired in September. Discussions about Chaeyeon's involvement in this comeback were ongoing.

DIA announced their last single under PocketDol Studio titled Rooting for You on September 6, 2022. Initially scheduled for September 15, the release was moved up to September 14 to coincide with their seventh anniversary since debut. Planned appearances on music shows were canceled due to Chaeyeon's injury. Despite contracts ending, member Yebin stated that DIA intends to continue activities and album releases collectively but under different agencies.
