HyunSung “Peace of Mind”Park

HyunSung Park is a South Korean mixed martial artist competing in UFC’s flyweight division. As of September 16, 2026, the UFC athlete profile lists him as active, identifies his nickname as “Peace of Mind,” and lists Tiger Muay Thai in Phuket, Thailand as his training base. Park is listed at 5 feet 7 inches tall, and his birth date is November 4, 1995.

Park turned professional in 2018 and previously held the Double G FC flyweight title. His route to the UFC came through Road to UFC’s inaugural flyweight tournament: he advanced through the bracket and submitted SeungGuk Choi on February 4, 2023 to earn a UFC contract. He then made his post-tournament UFC appearance against Shannon Ross in December 2023. UFC’s official profile records later bouts in 2025, including appearances against Carlos Hernandez, Tatsuro Taira and Bruno Silva; the profile lists the Silva bout of October 18, 2025 as his most recent fight.

A well-rounded finisher, Park has shown a particular preference for chokes and describes the jab as his favorite striking technique. UFC coverage has characterized him as capable across the major phases of MMA, with finishing instincts that complement a game built around pressure, grappling threats and clean boxing entries. Before beginning fight training, Park completed military service; he has said he began training at age 24 and left college during his freshman year.
