Seo Jang Hoon

Seo Jang-hoon (서장훈, born June 3, 1974, Seoul) is a former South Korean professional basketball center who became one of the country's most recognized television personalities. Standing 207 cm and weighing 116 kg, he dominated Korean courts for 15 years before pivoting entirely to entertainment.

At Yonsei University in the early 1990s, he played alongside a generation of college basketball stars whose popularity rivaled that of idol singers. That era was referenced in the drama Reply 1994, which depicted the cult following surrounding college basketball. Seo represented South Korea at the 1994 Hiroshima Asian Games, the 1998 Bangkok Asian Games, and the 2002 Busan Asian Games. His professional career spanned six KBL teams: Cheongju SK Knights, Seoul Samsung Thunders, Jeonju KCC Egis, Incheon Electroland Elephants, Changwon LG Sakers, and Busan KT Sonicboom. He retired in 2013 holding numerous KBL records, including two MVP awards (2000, 2006), two KBL Championships, and eight KBL Best 5 selections. He is listed among the KBL All-Time Legend 12.

After retirement, he pivoted to television and never looked back. His candid delivery and razor wit made him a natural anchor for advice and relationship-based programming. He became a regular on JTBC's Knowing Bros, co-hosted Divorce Camp, and joined SBS's My Ugly Duckling for eight years. In 2018, he won the Baeksang Arts Award for Best Variety Performer. Among Korean variety audiences he is also famous for his real estate portfolio -- the "building owner" (건물주) persona that followed his frequent remarks about property investment became a cultural shorthand for the athlete-turned-wealthy-landlord archetype and generated its own recurring comedy across multiple shows.

In 2026, he joins Lee Hyori as co-host of Yes Man, a new love-themed reality variety show on JTBC, extending a television career that now spans more than a decade and shows no signs of slowing.
