Infinite F (Korean: 인피니트F; stylized as INFINITE F) is the second sub-group of South Korean boy band Infinite formed by Woollim Entertainment in 2014. The sub-group consists of Infinite vocalists: Sungyeol, L and Sungjong. The sub-group made their simultaneous Japanese and Korean debuts with the single albums Koi no Sign and Azure.
Infinite F first performed as an unofficial unit at Infinite's 1st Inspirit Inauguration on August 17. The trio did a cover of Orange Caramel's "Bangkok City" which was well received by fans.
Infinite F was officially announced at the One Great Step Returns encore concert, held February 28 and March 1. They also performed the song "Heartthrob" for the first time.

As part of Japanese promotions, a pop-up store was set up in Harajuku from November 17 to 30, selling various Infinite F goods and clothing items. In addition, the sub-group did a five-show showcase tour, performing in Osaka, Nagoya and Tokyo.
