Choi Yeon-jun, known mononymously as Yeonjun, is a South Korean singer, songwriter, and dancer best recognized as the oldest member of the globally popular boy band TOMORROW X TOGETHER (TXT). Fans searching for Yeonjun age want to know exactly how old he is, when he was born, and how his age fits into his career timeline — and the answer is straightforward: Yeonjun was born on September 13, 1999, in Bundang District, Seongnam, South Korea, which makes him 26 years old as of 2026.
Understanding Yeonjun’s age also helps explain his role in TXT, since he is the group’s eldest member and one of the earliest trainees to join Big Hit Entertainment (now HYBE). This article covers his early life, education, career milestones, public life, and answers the most common questions people ask about his age and biography.
Early Life and Family
Discussions of Yeonjun age usually start with his roots, since his upbringing shaped the artist fans know today. Publicly available information about his family is limited — like many K-pop idols, Yeonjun and his agency have kept most personal family details, including his parents’ names and occupations, out of the public record. What is confirmed comes from interviews and verified biographical sources:
- Yeonjun was born September 13, 1999, in Bundang District, Seongnam, South Korea (some profiles list his hometown as Seongbuk District, Seoul).
- He is an only child, a detail he has mentioned in interviews and fan content.
- He lived in San Jose, California, for about two years as a child (around age 9) to learn English, before returning to South Korea.
- He grew up immersed in the arts early, later attending an arts-focused high school — a path that lines up closely with his age at the time he began training.
- His parents’ names, professions, and other private family details have not been publicly disclosed, and there is no reliable, verified source confirming this information — so it’s left out here rather than guessed at.
- Because so much of his early life took place before he was a public figure, most detailed family information simply isn’t part of the public record, regardless of what some fan sites may claim.
Given his age at his 2019 debut (19), and the fact that he trained for four years before that, Yeonjun’s early life was largely defined by preparation for his idol career rather than public visibility.

Education
Yeonjun’s education timeline is closely tied to his age, since his school years overlapped with the start of his idol training.
- He attended Seoul Jeongdeok Elementary School before his time studying in the United States.
- He passed through several middle and high schools, including Hongik University College of Education Middle School and Bulgok High School, before transferring.
- He ultimately attended Korea Arts High School in the Music Department, a common path for aspiring K-pop idols of his generation.
- At the age most students are finishing high school, Yeonjun was already deep into his four years of trainee work at Big Hit Entertainment, which he began around age 14–15.
- After high school, he enrolled at Global Cyber University, reportedly in a broadcasting/entertainment-related program — a flexible option that let him continue his idol career at the same age he’d otherwise be a full-time university student.
- Exact graduation dates and Yeonjun’s precise age at each academic milestone are not consistently documented across sources, so specific graduation ages should be treated as approximate rather than confirmed.
His education path illustrates how, from a young age, his schooling and artistic training ran in parallel — a common trajectory for idols debuting in their late teens.
Career
Yeonjun’s career timeline is often the first thing people cross-reference with his age, since he was still a teenager when TXT debuted. He trained for four years under Big Hit Entertainment before becoming the first TXT member publicly revealed, and by the time of his debut at age 19, he had years of preparation behind him.
- Pre-debut (2014–2019): Yeonjun trained for four years, reportedly after a stint as a trainee elsewhere. During this period, he was known internally for consistently placing first in monthly evaluations across dance, vocals, and rap.
- 2018: Before his official debut, and while still a teenager, Yeonjun appeared as a backup dancer during BTS member V’s (Kim Taehyung) promotions for “Singularity.”
- March 2019: At 19 years old, Yeonjun debuted with TXT via their first mini-album, “The Dream Chapter: STAR.” He was the first member introduced to the public.
- 2020–2021: TXT’s discography and international fanbase expanded rapidly during this stretch of his early-to-mid twenties.
- 2022: Yeonjun began hosting SBS’s music show “Inkigayo,” a notable solo milestone reflecting his growing individual profile at age 22–23. The same year, he became an ambassador and guest creative director for the streetwear brand Privé Alliance, and released the single “PS5” with Salem Ilese and TXT’s Taehyun.
- 2022–2024: TXT toured internationally with “Act: Lovesick” and “Act: Sweet Mirage,” further boosting Yeonjun’s visibility as he moved through his early twenties.
- April 2024: He stepped down from hosting “Inkigayo” after roughly two years.
- 2024: Named a global ambassador for Moncler, adding to his fashion industry presence at age 24–25.

Relationships and Public Life
As with many active K-pop idols, Yeonjun’s romantic life is not something he or his agency has publicly confirmed, and treating unverified dating rumors as fact wouldn’t be accurate. What can be said reliably:
- Yeonjun has not publicly confirmed being in a relationship or married, which is typical for idols under HYBE-affiliated labels, where such matters are generally kept private regardless of age.
- He’s known publicly for his fashion sense, having walked as Miu Miu’s first-ever K-pop idol runway model, and for his easygoing, humorous personality showcased during his Inkigayo hosting years.
- Any “dating rumors” or personal controversies circulated on fan and gossip sites are speculative and not confirmed by verified sources, so they aren’t included here.
Net Worth
Yeonjun’s net worth is frequently searched alongside his age, but there is no officially confirmed figure — HYBE and its labels don’t publish individual member earnings, and idol pay structures (including TXT’s revenue-sharing contracts) aren’t public. Online estimates vary widely and should be treated as rough, unverified approximations rather than facts:
| Category | Estimate/Details |
|---|---|
| Estimated Net Worth | Roughly $1.2 million–$6 million (estimates vary significantly by source) |
| Primary Income Sources | TXT album sales, world tours, merchandise, solo music, brand endorsements |
| Brand Deals | Privé Alliance (ambassador/guest creative director), Moncler (global ambassador) |
| Official Confirmation | None — all figures are third-party estimates, not verified financial disclosures |
Because these numbers come from celebrity-net-worth websites rather than audited or officially disclosed sources, they should be read as speculative ballparks, not confirmed wealth figures.
Other Ventures
Outside of TXT, Yeonjun has built a presence beyond music that reflects his growing profile as he’s aged into his mid-twenties:
- Hosted SBS’s “Inkigayo” for roughly two years (2022–2024), a notable solo media role.
- Serves as a global brand ambassador for Moncler and previously held an ambassador/guest creative director role with Privé Alliance, including a limited capsule collection.
- Became the first K-pop idol to walk in a Miu Miu runway show, expanding his profile in high fashion.
- Released a solo mixtape (“YEONJUN”) and solo EP (“No Labels: Part 01”), both of which he co-wrote, showcasing songwriting credits alongside his performing career.
- Maintains an active presence across TXT’s official channels and social media, where the group has amassed hundreds of millions of views.
Charitable Work
There is limited verified public information specifically detailing Yeonjun’s individual philanthropic activities separate from TXT as a group. Rather than speculate, it’s worth noting: K-pop idols and their agencies do periodically participate in charitable donations and fan-funded charity projects tied to birthdays or debut anniversaries, but no confirmed, individually attributed charitable initiative for Yeonjun is documented in reliable sources at this time.
