"Bo Peep Bo Peep" is a song by South Korean girl group T-ara. It is the first lead track (of two) from the album Absolute First Album, the other being "Like The First Time" (Korean: 처음처럼). The song won 5 weekly number one awards on KBS Music Bank and SBS Inkigayo. It was later re-recorded in Japanese for the group's debut single, which was released on September 28, 2011. The single has sold a total of more than 87,168 copies to date, peaking at number one on Oricon's weekly chart. The single was certified Gold for a shipment of over 100,000 paid downloads by the RIAJ.

For the group's comeback, T-ara released music video teasers for the songs "Bo Peep Bo Peep" and "Like the First Time". Around 9,000 netizens from over 9 music portal sites voted in a poll determining which song will become the album's title track, but despite "Like the First Time" being the winning song and lead track to the album, the group promoted "Bo Peep Bo Peep" on music programs after it was well received by critics who felt that it would be the group's first hit. The group held their comeback stage on KBS Music Bank on December 4.

On August 4, 2011, it was announced that T-ara would be debuting in Japan with a Japanese version of "Bo Peep Bo Peep". The single was released on September 28 as two limited editions and a regular edition, with a Japanese version of their song "I Go Crazy Because of You" as the accompanying b-side. The music video was released on September 1 on the Japanese cable television network Space Shower TV. The single debuted on Oricon's Daily Chart at No. 1 with 20,068 copies sold on the first day. They are the first Korean girl group to achieve the number one spot and the third Korean group to reach the top three of the charts after MBLAQ's "Your Luv" and SHINee's "Replay-Kimi wa Boku no Everything". The single debuted at number one on Oricon's Weekly Chart with 49,712 copies sold, making them the first foreign group and also the first Korean girl group to debut at number one.
