SF9 에스에프나인 is a male group under FNC Entertainment. They're the company's first dance-focused male idol group. SF9’s label sunbaes are F.T. Island, CNBLUE, AOA, and N.Flying.
The name SF9 stands for “Sensation Feeling 9” which is meant to convey that the group’s impressive skill level and emotional lyrics will surprise the public, causing a sensation. The Korean word for nine 구 also sounds like the Chinese character 久, which means "long time" when used as a noun. This represents the group’s desire to last a long time.
The first buzz about the group started with photos taken at Incheon International Airport when they were headed to Japan to perform at FNC Kingdom 2015 on December 11. The group had 11 members at that time, including Jinkyu, who was also a Boys24 contestant, and FNC trainee Alex Bell. The next day on the 12th, teasers were released of nine members designated as the first batch of trainees under the Neoz School trainee system.
"Neoz School" was broadcast as a web series where the 9 members competed against each other to determine who would debut. Despite being pitted against each other, the members worked towards debut as a unit.
“You can see it as a competitive system, but we try not to look at it that way. We do hold onto that little hope that all 9 of us can do well, and all 9 of us can debut together.” -Chani
On May 3, on their official Neoz School homepage, FNC announced the latest class of trainees: Kim Chulmin, Kim Hwan, Seo Dongsung, and Oh Seungsuk. These four trainees would form Neoz Band, playing instruments with a musical style similar to FT Island, CNBlue, and N.Flying. The quartet is now known as Honeyst.
With the addition of new schoolmates, the first nine were now considered Neoz Dance and prepared to debut as a dance-heavy idol group.
In May of 2016, FNC Entertainment launched a survival show on Mnet called "d.o.b. (dance or band)," featuring trainees separated into two teams, Neoz Dance and Neoz Band. The winning group from the show would debut first. The dance team won the competition with their first track "K.O." and debuted later that year as SF9.

On August 27, they held their first pre-debut fan meeting, Surprise Festival 9, where they met with 99 fans. They later held their second fan meeting, Surprise Festival 9 Autumn Sports Day, where they met with 333 fans on September 25.
SF9’s debut single album Feeling Sensation with lead single "Fanfare" was released on October 5, 2016. The album debuted at 8th place and peaked at 6th place on the Gaon Album Chart. They made their official stage debut on October 6, 2016, on "M Countdown."
On January 12, 2017, in celebration of their 100th day anniversary, they announced through livestream that their fans will be called "Fantasy."
