Shin Eun-soo (신은수) is a South Korean actress born on October 23, 2002. She entered the entertainment industry in 2014 by joining JYP Entertainment, where she began training initially for a career as a singer and actress. Her career quickly took a different turn when she was chosen from among approximately 300 candidates to play the lead role in the fantasy film Vanishing Time: A Boy Who Returned.
Released in 2016, Vanishing Time made her acting debut alongside Gang Dong-won. Despite her lack of experience, her performance as Su-rin garnered attention and earned her the Popularity Award at the Korea Top Star Awards. That same year, she appeared in The Legend of the Blue Sea, in which she plays the teenage version of Se-hwa, a character portrayed as an adult by Jun Ji-hyun.
She continues her career with Magic School, Bad Dad and the science fiction movie Illang: The Wolf Brigade. In 2020, she played Jin Ha-young in Do Do Sol Sol La La Sol, before moving on to several projects in 2022: Bloody Heart, A Model Family and above all Summer Strike, in which she plays Kim Bom.
In 2023, Shin Eun-soo saw a renewed surge in popularity thanks to Twinkling Watermelon. In it, she plays Yoon Cheong-ah, a reserved young deaf woman—a role that became one of the most beloved of her career. She then joined the cast of Light Shop in 2024, playing the lead role of Joo Hyeon-joo.
In 2025, she plays the lead role in a romantic movie Love Untangled (A Medley of Feelings), in which she plays Park Se-ri. That same year, she left her former agency and signed with Management SOOP. She has also been cast in the series Hyeopban, in which she is set to play Lee Ru-ri.
Having made the transition from trainee to leading actress at a very young age, Shin Eun-soo has gradually distinguished herself through her portrayal of sensitive and often introverted characters, notably in Summer Strike and Twinkling Watermelon.
