Big Bang (Korean: 빅뱅; commonly stylized as BIGBANG) is a South Korean hip hop group formed by YG Entertainment in 2006. The group consists of G-Dragon, T.O.P, Taeyang, Daesung and formerly Seungri.

Big Bang have released several successful singles and EPs. Their first release, the EP Always (2007), spawned the number-one single Lies (Korean: 거짓말; Revised Romanization: Geojitmal). The follow-up EPs Hot Issue and Stand Up were similarly successful. After they received the Artist of the Year award from the M.net KM Music Festival and the Seoul Gayo Daesang Award, the group expanded their activities into Japan, releasing mini-albums and airplay singles. Their materials did not receive major promotion until the following year with the release of their first physical Japanese single, My Heaven. Since then, the group has attained considerable success in the country.

They became the first foreign group in Japan to receive the Japan Cable Broadcasting Award for Best Newcomer, and the first from Korea to receive the Japan Records award. In recent years, the members have branched out to do solo activities: Taeyang and G-Dragon have released solo materials while T.O.P, Daesung and Seungri have started acting (in both dramas and musicals) and participating in variety programs.

Representing Asia-Pacific, Big Bang emerged as the inaugural Best Worldwide Act winner of 2011 MTV Europe Music Awards (EMA) held at Belfast, Northern Ireland. There, apart from Queen, Big Bang was the only winner not from North America.

Fans of Big Bang are known officially as VIPs, after their single V.I.P.
