AOA Black was a subgroup of the South Korean girl group AOA, formed by FNC Entertainment in 2013. Youkyung left the agency of the group in October 2016, but would remain as a guest member for future activities. Choa left the group and sub-unit on June 30, 2017, while Mina left the group in May 2019, Jimin in July 2020, and Yuna in January 2021. Due to the departures of all members from the label and the main group, the subgroup was quietly disbanded immediately after Yuna left both. The subgroup was notable for their debut single album, "Moya".
