Park Ji-hoon is a South Korean singer and actor who first captured the public's attention as a child performer before skyrocketing to international fame as a member of the legendary project group Wanna One. Born on May 29, 1999, he began his career in the entertainment industry at a remarkably young age, debuting as a commercial model and child actor in 2006. This early start laid the foundation for a multifaceted career that would see him transition seamlessly from child star to teen idol and eventually to a respected solo artist and leading man. His journey from a young face in advertisements to a household name in K-pop and K-drama is a testament to his enduring talent and versatility.

Park Ji-hoon's life changed dramatically in 2017 when he participated in the second season of the reality competition series Produce 101. His charismatic performances, particularly his signature "wink" during the evaluation stage, made him an instant fan favorite. He ultimately placed second in the competition, earning a spot in the resulting boy group Wanna One. The group, which also featured members like Kang Daniel and Ong Seong-wu, became a monumental success in South Korea and across Asia, releasing multiple hit albums and embarking on sold-out tours. Park Ji-hoon's time with Wanna One from 2017 to 2019 established him as a top-tier idol, and the group's legacy continued with a brief reunion in 2021 and 2022, further solidifying their place in K-pop history.

Following the conclusion of Wanna One's initial activities, Park Ji-hoon launched his solo career with the release of his first extended play, O'Clock, in 2019.

He continued to build his discography with his debut studio album Message in 2020, which further explored themes of love and personal reflection. His solo work has been characterized by a blend of pop and R&B influences, allowing him to carve out a distinct identity separate from his group activities, and he has consistently released new music, cementing his status as a credible solo performer.

In addition to his flourishing music career, Park Ji-hoon has made a significant impact as an actor. After honing his skills in supporting roles, he landed his first leading role in the television series Weak Hero in 2022. The series, a gritty and intense high school drama, was a critical and commercial success, earning widespread praise for its action sequences and compelling storytelling. Park Ji-hoon’s portrayal of the intelligent but physically vulnerable student Yeon Si-eun was a breakout performance that showcased his dramatic range. He reprised the role in the second season of Weak Hero in 2025, demonstrating his commitment to the character and the growing franchise. His success in the role led to further opportunities, including the leading role in the historical film The King's Warden in 2026, marking his first major film project and expanding his repertoire into period cinema. Through his dual career as a singer and actor, Park Ji-hoon has proven himself to be one of the most versatile and enduring talents of his generation.
