A Pink (Korean: 에이핑크) is a seven-member South Korean girl group under A Cube Entertainment formed in 2011. The group consists of Park Cho-rong, Yoon Bo-mi, Jung Eun-ji, Son Na-eun, Hong Yoo-kyung, Kim Nam-joo and Oh Ha-young.

The group has released two Korean EPs and one studio album. They debuted on April 21, 2011, with "Mollayo" (몰라요; "I Don't Know") from their debut EP Seven Springs of A Pink on Mnet's M! Countdown. The group has also won numerous rookies awards at shows such as the 26th Golden Disk Awards, 21th Seoul Music Awards, and 13th Mnet Asian Music Awards. Their first music program win was on M! Countdown on January 5, 2012, for "My My" from their second EP Snow Pink.

The first trainee to be revealed as a member of Cube Entertainment's new girl group was Son Na-eun, who was featured in labelmate Beast's "Soom" (숨; "Breath"), "Beautiful" and "Niga Jeil Joha" (니가 제일 좋아; "I Like You the Best") music videos in late 2010. The second member revealed was the group's leader, Park Cho-rong, who was shown at the end of Beast's "Shock" Japanese music video. It was later revealed that the new girl group would be managed by a sub-division of Cube Entertainment known as A Cube Entertainment. On February 21, A Cube Entertainment set up an official Twitter account and revealed Oh Ha-young as the third member of A Pink. Jung Eun-ji was the fourth member revealed through A Cube's Twitter through a video of her singing a rendition of Jennifer Hudson's "Love You I Do". Hong Yoo-kyung was similarly revealed through an online video where she was playing the piano. Yoon Bo-mi and Kim Nam-joo were the last members to be revealed through Twitter.

Prior to the group's debut, the documentary A Pink News aired on the Korean cable channel TrendE. The show chronicled the debut process of the members of A Pink. The pilot episode of A Pink News was aired on March 11. Each episode featured a different celebrity guest as its anchorman. Among the celebrity guests of the show were G.NA, Mario, MBLAQ's Seung Ho and G.O, Beast, 4minute, 2AM's Jinwoon, Infinite's Sunggyu and Sungjong, and Secret's Sunhwa and Hyosung.
On April 13, the music video teaser for A Pink's debut EP, Seven Springs of A Pink, was released. The theme of the teaser was the spring season and the idea of innocent beauty. The group released the album and the music video for its lead single, "Mollayo" (몰라요; "I Don't Know"), on April 19. The album featured five songs, including "It Girl" and "Wishlist". The music video for "Mollayo" featured Beast's Gi Kwang. A Pink made their debut stage performance with "Mollayo" on Mnet's M! Countdown on April 21 to promote their album. During the group's first official fanmeet, it was revealed that their official fan club name is 'Pink Panda', a play on the name of the group and the Korean word for 'fan' (팬, paen). Following their promotions for "I Don't Know", the group promoted "It Girl" on the weekly music shows. A Pink also recorded the song "Uri Geunyang Saranghage Haejuseyo" (우리 그냥 사랑하게 해주세요; "Please Let Us Love") for the popular SBS drama, Protect the Boss. The soundtrack was released in September 2011.

In November 2011, A Pink began recording a new reality television show called Birth of a Family with boy band Infinite. The show followed the journey of the two idol groups in taking care of abandoned and mistreated animals over the course of eight weeks. The first episode aired on November 12.

The group released their second EP, Snow Pink, on November 22, featuring the lead single "My My". The album featured five tracks, including "Yeah" and "Prince". The music video teaser for "My My" was released on November 21. Promotions for "My My" began on November 25, on KBS' Music Bank. The song was particularly noted for having a sound reminiscent of girl groups of the early 2000s, such as S.E.S and Fin.K.L. During their promotions for "My My", the group opened up a one-day idol tea cafe, serving visiting fans to raise profits for charity and preparing food and drinks themselves. The members also auctioned off some of their personal items for charity.

On November 29, A Pink were awarded the Best New Female Artist award at the 13th Mnet Asian Music Awards. A Pink released a song with Beast called "Skinny Baby" for the school uniform brand Skool Looks on December 26. The track was written by Kim Taewan and Yoon Sangjo.

On January 5, 2012, the group won their very first music show award on Mnet's M! Countdown for "My My".

A Pink's Eunji and Beast's Yoseob released the music video for their duet song "Love Day" on March 13. The full single, titled "A CUBE For Season # Green", was released the next day. Eunji and Yoseob performed the song on the April 7 episode of MBC's Show! Music Core.

The group performed at the Kool Haus in Toronto, Canada, to about 1,000-1,600 fans on March 21, 2012.

On April 19, A Pink released "4 Wol 19 Il" (4월 19일; "April 19th") as a gift for their fans to celebrate their one year anniversary. The song was composed by Kim Jin-hwan, and the lyrics were personally written by the group's leader, Park Cho-rong.

A Pink released their first studio album, Une Annee, on May 9. The group promoted the album by making weekly appearances on several music programs and performing "Hush". A Pink released their third single from the album, "Bubibu", on July 6. The single was chosen by fans through an internet polling on Mnet's official website. The group began follow-up promotions for "Bubibu" on July 7.
