Nassourdine Imavov (born March 1, 1995, in Khasavyurt, Dagestan) is a French mixed martial artist competing at middleweight in the UFC. Raised in an ethnic Kumyk family, he moved to Salon-de-Provence, France, at age nine, took up boxing, and later relocated to Paris at 19 with his brother Daguir to train at MMA Factory under Fernand Lopez. In late 2023 he shifted his primary training to Venum Training Camp under coach Nicolas Ott.
Imavov turned professional in 2016 and built an 8–2 start on the European circuit, winning the Thunderstrike Fight League welterweight title and stopping former UFC fighter Jonathan Meunier at ARES FC 1 (December 14, 2019). He debuted in the UFC on October 4, 2020, defeating Jordan Williams by unanimous decision, then added standout wins over Ian Heinisch (TKO, July 24, 2021), Edmen Shahbazyan (TKO, November 6, 2021), and Joaquin Buckley (UD, September 3, 2022). His early UFC run also featured a setback against Sean Strickland (UD, January 14, 2023) and a no-contest with Chris Curtis (June 10, 2023).
Rebounding in 2024–2025, Imavov defeated Roman Dolidze (MD, February 3, 2024), stopped Jared Cannonier (TKO, June 8, 2024), outpointed Brendan Allen in Paris (UD, September 28, 2024), and scored a signature second-round TKO of former champion Israel Adesanya in Riyadh (February 1, 2025). As of August 19, 2025, he is ranked among the top contenders at middleweight, positioning him for title contention on the strength of that four-fight winning streak.
