Lee Jae-yoon

Lee Jae-yoon is a South Korean singer, dancer, actor, and model who serves as a lead vocalist and dancer for the K-pop group SF9. Born in Busan, he stands out for his distinct vocal tone and his successful transition from pop idol to musical theater performer. He performs under the stage name Jae Yoon to distinguish himself from other actors with the same birth name.

His career began after winning the Mnet survival show d.o.b.: Dance or Band in 2016, which led directly to his debut with SF9. Beyond group activities, he has built a reputation for emotional live performances and significant roles in major Korean musical productions like Seopyeonje. [edit]

Born on August 9, 1994, in Busan, South Korea, Lee Jae-yoon showed an early aptitude for performance arts. Unlike many trainees who join agencies immediately after middle school, he spent several years honing his skills before entering the professional circuit. His path to stardom was paved through FNC Entertainment's rigorous rookie training program known as Neoz School, where he focused intensely on dance and vocals.

In 2016, he entered the competitive landscape of reality television by joining the nine-member dance team NEOZ Dance for the Mnet survival show d.o.b.: Dance or Band. The competition required participants to showcase both technical dance ability and vocal stability against various bands and dance groups. NEOZ Dance emerged victorious, securing their spot as FNC Entertainment's first male dance group. This victory marked the end of his pre-debut training phase and set the stage for his official entry into the entertainment industry. [edit]

Following his win on d.o.b., Lee Jae-yoon debuted as a member of SF9 on October 5, 2016, with the single album Fanfare. As one of the group's main vocalists, he quickly became central to their live performances, known for maintaining pitch during high-energy choreography. The group released several successful albums including Breaking Sensation in 2017 and Morph in 2019, establishing a strong presence in the K-pop scene.

While continuing his work with SF9, he expanded his portfolio into acting and musical theater. His web drama debut came in 2016 with Click Your Heart, but it was his role in the 2021 web drama Love in Black Hole that showcased his potential as a lead actor. A significant milestone occurred in 2022 when he joined the cast of the long-running musical Seopyeonje. His performance in this critically acclaimed production demonstrated his versatility and growth beyond pop music, earning him praise within the musical community. He also appeared in the musical Another Miss Oh during the same period. By 2026, he remains an active member of SF9 while balancing a steady schedule of musical roles and occasional variety appearances. [edit]

Lee Jae-yoon is portrayed as a talented, humble, and hardworking idol who takes his craft seriously. Media coverage emphasizes his dedication to musical theater, often describing him as a 'quiet leader' within SF9 due to his professionalism and supportive nature toward fellow members. His aesthetic is clean and stylish, fitting the modern K-pop idol image while allowing for the dramatic transformations required for stage roles. He is known for his warm interactions with fans and his genuine gratitude for their support. [edit]

iFANN has evaluated Lee Jae-yoon but he does not currently hold a placement in the published Global Top 1,000 rankings as of September 2026. While he enjoys significant popularity within the K-pop community, his individual fame ranking has not yet reached the threshold for a specific numerical position in the global index. His fanbase, known as SF9N (or simply Nine), is highly organized and active. Fans are known for streaming parties, birthday campaigns, and charity drives in the group's name. They often coordinate lighting stick colors during concerts and launch initiatives to boost streaming numbers upon album releases. Lee Jae-yoon interacts with them through fan letters, meet-and-greets, and social media comments, fostering a loyal and engaged community. [edit]

Lee Jae-yoon frequently references his hometown of Busan in interviews, often sharing stories about his regional roots despite his global fame. Fans often cite his live vocal stability during concerts as a defining trait, noting his ability to sing complex ballads while performing difficult dance routines. He was one of the few trainees selected from Neoz School to compete in d.o.b., highlighting his early talent among peers. His casting in Seopyeonje was considered a major validation of his artistic growth, marking a shift from idol to respected stage actor. Another interesting fact is that he uses the stage name Jae Yoon specifically to avoid confusion with the more famous actor Lee Jae-yoon born in 1984. [edit]

Lee Jae-yoon keeps his family life private, rarely discussing his parents or siblings in public interviews. He maintains a close bond with his younger brother, though details about his sibling are not widely publicized. There are no confirmed reports of pets or specific household arrangements beyond his standard living situation in Seoul. He focuses primarily on his career and rarely shares personal family anecdotes on social media, preferring to keep the spotlight on his professional achievements. [edit]

Unlike the actor Lee Jae-yoon (born 1984), who has discussed dating preferences in interviews, the SF9 member has not publicly disclosed any specific partners. Rumors occasionally circulate on fan forums regarding potential pairings with fellow idols or actresses, but none have been substantiated by the artist, his agency, or reliable news outlets.

As of 2026, he is single and focuses primarily on his career in music and theater.

iFANN currently estimates Lee Jae-yoon's net worth at approximately $2 million USD. This figure reflects his earnings as a stable member of the third-generation group SF9, combined with income from his solo activities in musical theater and original soundtracks. His financial growth over recent years has been steady, driven by consistent album sales, concert tours, and endorsement deals typical for idols of his stature.

Revenue streams include digital music sales and streaming royalties from SF9's discography, ticket sales from domestic and international fan meetings, and partnerships with lifestyle and fashion brands. Additional income comes from his work in musicals like Seopyeonje and Founded, as well as OST recordings for popular dramas. While exact figures are managed privately by FNC Entertainment, industry standards for established members of top-tier groups suggest this valuation aligns with his current market position. [edit]

Lee Jae-yoon shares in the accolades won by SF9, including Best New Male Group awards. However, there are no records of him winning major individual awards such as Best Vocalist or Best Actor at major ceremonies like the Golden Disc Awards or Baeksang Arts Awards as of 2026. His participation in Seopyeonje received critical praise and nominations within the musical community, though specific individual wins are not widely cataloged in international databases. [edit]
