Seo Yu Na is a South Korean singer, dancer, actress, yoga instructor and former member of AOA (에이오에이). She graduated from Gyeonggi Girls' High School.

In April 2012, FNC Entertainment (FNC엔터테인먼트) revealed plans to debut a new group that will have a rotating concept between a girl group and a rock/indie band, with 7 members being part of both and one member being only part of the band.

She made her debut in July 2012 as the group's main vocalist and keyboardist with their first single album, "Angel's Story", to very little success. The group continued to struggle early on, and FNC decided to create the sub-unit AOA BLACK (AOA 블랙), debuting in July 2013 with the single album "Moya". AOA did not find success until mid-2014 when the single "Heart Attack" became one of the most downloaded songs of 2015 and was also one of the longest-charting singles on Melon's Top 100 Chart. Afterwards, the group kept releasing successful materials.

Then, she became part of a new sub-unit, AOA CREAM (AOA 크림), in July 2016. They debuted with the single "I'm Jelly Baby" but became inactive soon after promotions ended.

She and composer Kang Jung Hoon, better known as Friday of the music production duo GALACKTIKA (갈락티카), got married in February 2024. She is also represented by their company and focuses on her acting career in both TV and musical theater.

Her first child was born on November 27, 2025.
