Ateba Gautier

Ateba Abega Gautier (born 10 April 2002), is a Cameroonian professional mixed martial artist competing in the middleweight division of the Ultimate Fighting Championship (UFC).

Gautier was raised in Douala, Cameroon, in a neighborhood where violence was common. As a teenager he frequently became involved in street fights, which he has described as a way to gain respect and avoid being bullied. He has recalled several dangerous encounters during this period, including being stabbed with a screwdriver in one altercation.

He began training in combat sports at the age of 17 as a way to stay off the streets. Gautier initially trained at the Mboa Sports Association, where he and another athlete were supported as prospects with the long‑term goal of reaching the UFC. He did not grow up with knowledge of mixed martial arts; he started practicing sambo at 18 and transitioned to MMA at 19 at the encouragement of his coach.

Before turning professional, Gautier competed in amateur combat sports, earning a silver medal at the 2024 African Sambo Championships in the 88kg division and winning the UAE Young Muay Thai Championship. On 10 March 2022, he left Cameroon for Manchester, England, where he joined Manchester Top Team under coach Carl Prince to pursue full‑time training.

Gautier made his professional debut in 2021, competing in regional promotions in Africa and Europe. His early career included several knockout victories, and he suffered his first professional defeat by split decision in 2022.

On 17 September 2024, Gautier competed on Dana White's Contender Series, where he defeated Yura Naito by technical knockout in the second round. The victory earned him a contract with the UFC.

Gautier made his UFC debut on 29 March 2025 at UFC on ESPN 64, where he defeated José Medina by first-round knockout. This fight earned him his first Performance of the Night award.

Gautier was originally scheduled to face Robert Valentin on 12 July 2025 at UFC on ESPN 70. However, the bout was moved to 19 July 2025 at UFC 318 for undisclosed reasons where he won the bout by technical knockout early in the first round. This fight earned him another Performance of the Night award.

Gautier was originally scheduled to face former LFA Middleweight Champion Osman Diaz on 4 October 2025 at UFC 320. However, Diaz pulled out from the event due to a medical issue and was replaced by promotional newcomer Tre'ston Vines. Gautier won the bout by knockout in the first round via elbows and punches.

Gautier faced Andrey Pulyaev on 24 January 2026, at UFC 324 and won the bout by unanimous decision.

Gautier ended up facing Osman Diaz on 9 May 2026 at UFC 328. He won the fight via technical knockout in round two.

Gautier is pursuing a degree in geology alongside his fighting career. He comes from a large family in Cameroon, where his brothers help care for his mother while he trains abroad. His nickname, Silent Assassin, was given by his coach due to his quiet demeanor outside competition. He has cited teammate Lerone Murphy as a major influence and mentor.
