Anissa Meksen (Arabic: أنيسة مكسن; born 29 April 1988) is a French-Algerian[3] professional kickboxer, Muay Thai fighter, Savateur, and boxer.

Known for her versatile fighting style which is characterized by her sharp striking, footwork, and ring intelligence,[4] Meksen is regarded as one of the greatest kickboxers of her generation.

The following year, she won the WFC European Muay Thai title (-52 kg) when she beat Yolande Alonso via technical knockout in the second round.

During World Muaythai Auspicious Celebration, Meksen fought Monoprangroj Kampetch for the S1 Savante Bantamweight title.

[17] After winning her next two fights, Meksen challenged Sor Tawanrung Kwanjai for the WPMF World Muay Thai title.

[18] Meksen won her next two fights, before once against contesting the WPMF World Muay Thai title, this time against Hongthong Liangbrasert.

[22] Meksen then had a five fight winning streak, before contesting the WFC European Bantamweight Muay Thai title against Yolande Alonso.

Meksen lost a highly controversial split decision, that would be dubbed the "Robbery of the Year" by Combat Press.

[36] During ONE On TNT IV, Chatri Sityodtong announced that Meksen will make her promotional debut in a women's strawweight kickboxing-bout against Italian kickboxer and Nak Muay Featherweight Martine Michieletto, on May 28, 2021, at ONE Empower.

After the weigh-ins, ONE Championship posted a video to social media, showing Meksen returning the 20% back to Banchamek as a sign of respect for taking the fight.

[44] During her in-ring interview with Mitch Chilson following her victory over Dangkongfah Banchamek, ONE Championship announced Meksen would face Stamp Fairtex in a Mixed Rules-bout at ONE on Prime Video 6 on January 14, 2023, at the Impact, Muang Thong Thani in Bangkok.

However, Meksen failed to appear at the weigh-ins and the fight was scrapped, with Fairtex instead being matched up against Anna "Supergirl" Jaroonsak in a kickboxing bout.

Meksen responded by reminding the fans that she did not appear due to a family issue and that she would be interested in fighting Fairtex for the Interim ONE Atomweight Kickboxing Championship at ONE on Prime Video 7, after being "shocked" to find out that there would be no decision in her exhibition Mixed Rules-bout, if the fight had no winner after the regulated time, which she would never agree to if she knew in advance.

Meksen was also unhappy with CEO Chatri Sityodtong stating: “He was aware of the situation but preferred to announce that I was ‘unwell’ to clear his name and not take responsibility for my absence at the conference.

On October 31, 2023, it was announced that Meksen would face Phetjee Jaa Or.Meekun for the interim ONE Women's Atomweight Kickboxing World Championship at ONE Friday Fights 46 on December 22, 2023.

[50] Meksen was expected to face Jackie Buntan for the inaugural ONE Women's Strawweight Kickboxing World Championship on July 6, 2024, at ONE Fight Night 23.
