The Bare Knuckle Fighting Championship (BKFC) is an American bare-knuckle boxing promotion based in Philadelphia.

BKFC is the first promotion to hold an official state-sanctioned and commissioned bare-knuckle boxing event in the United States since 1889.

[2][3][4] BKFC's inaugural event, which took place on June 2, 2018, featured the first American-sanctioned, women's bare-knuckle fight in modern history.

[5] The Bare-Knuckle Boxing Hall of Fame recognized this milestone and awarded the victor of this contest, Bec Rawlings, with the National Police Gazette World Diamond Belt several days later.

[7] In February 2019, former UFC light heavyweight title contender Anthony Johnson announced that he will be joining the company in an administrative role.

[12] BKFC Thailand held its inaugural event on December 18, 2021, sub-titled "The Game Changer".

[13] The event featured big names like former two-division WBC boxing champion Sirimongkol Singmanasak and Muay Thai fighter Sinsamut Klinmee.

[14] On February 24, 2022, David Feldman announced on The MMA Hour that TrillerNet had acquired a majority stake of BKFC.

Competitors in the Prospects Series include previous participants at BKFC open tryouts, as well as athletes with backgrounds in boxing, Muay Thai, and mixed martial arts.

[23] At Super Rizin 3 on July 28, 2024, Charisa Sigal, Tai Emery, Takaki Soya, and John Dodson all fought in bare-knucking bouts on the undercard.

These scratch lines are based on the Broughton Rules, which governed bare knuckle fighting in the 19th century.

The rules permit the use of kicks, punches, elbows, and knees, but explicitly prohibit trips and sweeps.

[25][26] BKFC Thailand held the first special rules Bare Knuckle Thai bout, featuring Muay Thai legends Buakaw Banchamek and Saenchai, at BKFC Thailand 5: Legends of Siam on November 4, 2023.

[27] After the Triller acquisition, Fite announced in February 2023 that all BKFC events would be included for Fite+ subscribers.
