Mamamoo (Hangul: 마마무), sometimes stylized as MAMAMOO, is a South Korean girl group formed by Rainbow Bridge World (formerly WA Entertainment) in 2014. The group officially debuted on June 18, 2014 with the song "Mr. Ambiguous". Their debut was considered by some critics as one of the best K-pop debuts of 2014. They are recognized for their retro, jazz, and R&B concepts and strong vocal performances.

Prior to their official debut, Mamamoo collaborated with several artists. Their first collaboration titled "Don't Be Happy" with Bumkey was released on January 8, 2014. A second collaboration with K.Will titled "Peppermint Chocolate" featuring Wheesung was released on February 11, 2014. "Peppermint Chocolate" ranked 11th on the Gaon Digital Chart in its first week. On May 30, Mamamoo released a third collaboration with rap duo Geeks called "Hi Hi Ha He Ho".

The group made their official debut on June 19 with lead single "Mr. Ambiguous" from their first mini album Hello. The music video for "Mr. Ambiguous" contained cameo appearances from many well-known K-pop industry figures such as CNBLUE's Jonghyun, Baek Ji-young, Wheesung, Jung Joon-young, Bumkey, K.Will, and Rhymer of Brand New Music. The album contained three previously released collaborations and four new songs. The group made their first live appearance on the June 19 episode of M! Countdown. On June 27, Mamamoo performed "Peppermint Chocolate" with K.Will and VIXX's Ravi on the Music Bank "Half-Year" Special. On July 5, the group held a guerilla concert at Hongik University in Hongdae, Seoul. In July, Mamamoo released their first original soundtrack contribution titled "Love Lane" for the Korean drama Marriage, Not Dating.
