Miss A (Hangul: 미쓰에이) was a South Korean girl group, formed by JYP Entertainment in 2010, consisting of Fei, Jia, Min, and Suzy. Jia and Min left the group in May 2016 and November 2017, respectively, before the group officially disbanded on December 27, 2017.

Originally, the group consisted of five trainees who were formed by JYP Entertainment in 2010. They first appeared in Chinese variety shows performing dance routines and songs as the "Chinese Wonder Girls," with Woo Hyerim as a member, who was placed in Wonder Girls soon before Miss A's debut in order to replace Sunmi. In March 2010, fifteen-year-old trainee Bae Suzy joined the group which, then a trio became known as 'Miss A'. The group signed with the Samsung Electronics group in China and released a song used for the commercial called "Love Again" for the Samsung Beat Festival. Lee Min Young, a solo artist and a long-time trainee in America, also made a cameo appearance in the music video, and joined the group for their South Korean debut in April 2010.
