SF9 is a South Korean boy group formed by FNC Entertainment. The group debuted on October 5, 2016, with Feeling Sensation and established itself through ambitious stage choreography, dramatic styling and dance-pop recordings. Although its original name refers to nine members, the official lineup now includes eight artists: Youngbin, Inseong, Jaeyoon, Dawon, Zuho, Yoo Taeyang, Hwiyoung and Chani.

SF9 expanded its musical range through tracks including “Good Guy,” “Summer Breeze,” “Tear Drop” and “Puzzle.” Its 2025 EP LOVE RACE was followed by About Love in March 2026 and the second full-length album TENACITY on August 26, 2026. The latter features the official title-track music video “Without Wings.”

The group’s touring, music releases and acting-related activities are accompanied by distinct individual careers. Inseong, Yoo Taeyang and Hwiyoung have documented independently issued solo music; they are marked SOLO below. Individual group-song lines or appearances alone do not qualify other members for a solo discography designation.

Official FNC and SF9 Japan resources provide a core record of the current lineup, music and activities. Exact participation in a particular campaign should be checked against that promotion’s credits and official photography rather than assumed from full-group membership.
