OH HAYOUNG is a vocalist and dancer of Apink whose career began with the group’s debut in April 2011. She has continued to perform with the long-running group and has pursued singing, acting and online video projects under her own name.

In August 2019, Hayoung released the solo mini album “OH!”, led by the music video single “Don’t Make Me Laugh”. This album is independently credited to Hayoung rather than Apink. Her solo catalog is therefore kept separate from the group’s releases and from other members’ recordings.

Hayoung was the youngest member at Apink’s 2011 debut and has continued performing in the group’s later releases. She launched an independently credited solo music career with the mini album OH! in August 2019, led by Don’t Make Me Laugh. Individual acting and web activities are separate from her group and solo discographies.
