Kim You-jung is a South Korean actress who has practically grown up in front of the Korean public.

She was born on September 22, 1999 (26 years old) in Seongdong District, Seoul, South Korea.

She is one of those rare child stars who turned her early fame into a long, layered acting career across film, television, theatre, and now global streaming. Her work moves easily between historical dramas, romantic comedies, and dark psychological roles.

Kim started acting in 2003 at the age of four, and quickly became the face Koreans grew up with on screen. She first led a drama as an adult with the historical romance Love in the Moonlight (2016), which became a national hit alongside Park Bo-gum.

Her career also includes Moon Embracing the Sun (2012), Backstreet Rookie (2020), Lovers of the Red Sky (2021), the Netflix film 20th Century Girl (2022), My Demon (2023 to 2024), and the psychological thriller Dear X (2025).

In September 2025, she was honoured as the inaugural recipient of the Busan International Actors Award at the 30th Busan International Film Festival, a landmark moment in her transition from child star to leading lady.
