Seohyun was born Seo Juhyun ( 서주현) on June 28,1991 in Seoul and is the only child in her family.
Her mother was a chairman at a piano school and Seohyun was taught how to play piano, as well as violin and traditional Korean drums in her early childhood. She also learned horseback riding and skating as a child. Her parents did not encourage her to become a celebrity but Seohyun credited them as the ones who helped her choose her career path by letting her experience different things.

As a fifth grader, Seohyun was discovered by a talent scout while riding in a subway train. She sang children's songs for her audition at SM Entertainment and was accepted as a trainee. Seohyun cited BoA, S.E.S and Fin.K.L as her main influences to become a singer, expressing "I thought it was cool to show and communicate the emotions through songs".

In August 2007, Seohyun made her official debut as the youngest member of girl group Girls' Generation.
In April 2012, she debuted again under subunit TTS along bandmates Taeyeon and Tiffany.
In January 2017, she finally debuted as a solo artist with Don't Say No (EP).
She left SM Ent. in October 2017 and signed with Namoo Actors in March 2019.
