Park Shi Eun

Park Si Eun is a South Korean singer, dancer, actress and member of STAYC (스테이씨). She graduated from Goyang Arts High School and is enrolled in the Theater program at Chung-Ang University. She is the daughter of legendary 1980s singer Park Nam Jung. She spent 4 years as a trainee, including time at JYP Entertainment.

Before singing, she was a child actress who made her debut in 2014 as part of the EBS children's TV series Pluto Squad (플루토 비밀결사대). In 2018, she won Best Young Actress during the SBS Drama Awards for her role in Thirty but Seventeen (서른이지만 열일곱입니다).

She joined High Up Entertainment (하이업엔터테인먼트) in mid-2019, and she made her debut in November 2020 as STAYC's main vocalist with their first single album, Star To A Young Culture. In August 2023, all the members decided to take turns as leaders, so she and Se Eun became co-leaders for the time being.
