Strawweight
The strawweight division is the most technically dense women's division in the UFC. 115 pounds produces fighters who prioritize technique, speed, and ring generalship over raw power, and the result is some of the most watchable MMA in the sport. The division has had five different champions since its creation in 2014, and no one has dominated the way Joanna Jedrzejczyk did for two years — which makes every title fight feel genuinely contested.
Zhang Weili currently sits at the top as the most complete fighter at the weight, combining striking power with legitimate wrestling in a package that the division has found no reliable answer for. The challenger pool is the deepest it has ever been, with Tatiana Suarez's undefeated wrestling resume, Yan Xiaonan's relentless pressure, and several young contenders pushing toward the title conversation.
This is the chess match division. These fights play out in layers — feints, distance management, takedown threats opening up strikes. The strawweights are the ones who make MMA look like a pure sport. If you want technical, this is your weight class.
Flyweight
The flyweight division was essentially built around Valentina Shevchenko, who dominated it so completely for five years that people forgot it existed independently of her. Seven title defenses. When Alexa Grasso submitted her at UFC 285 in one of the biggest upsets in women's MMA history, the division opened up in ways it had not been open since its creation.
Grasso has proven her championship run was no fluke, winning the rematch against Shevchenko and establishing herself as the legitimate queen of the flyweight division. A Mexican champion who has become a genuine sports star in Mexico, Grasso defends the title with the same pressure-fighting, submission-threatening style that made her champion in the first place.
Flyweight is where wrestling meets elite striking. The division is physical in a way that strawweight is not — these are bigger athletes who hit harder — but the technical ceiling is just as high. Shevchenko's presence alone raised the floor of what every other flyweight had to become.
Bantamweight
Bantamweight is the original women's UFC division — the one created specifically for Ronda Rousey in 2012 that started everything. Its history is the history of women's MMA in the UFC: Rousey's dominance, the Tate-Holm transition, Nunes's extraordinary reign, the Pena upset, and now a division that is more competitive than it has ever been.
Julianna Pena is the current champion after an up-and-down ride with Amanda Nunes that included the biggest upset in women's MMA history. The division now has depth it lacked in the Nunes era — multiple serious contenders, the arrival of Kayla Harrison from the PFL, and the continued presence of foundational figures like Holly Holm.
This is where the history lives. Amanda Nunes, Ronda Rousey, Miesha Tate, Holly Holm — bantamweight has had more iconic moments than any other women's division. It is the main stage. When something historic happens in women's MMA, it usually happens here.
Featherweight
InactiveThe women's featherweight division at 145 pounds has been one of the more troubled weights in UFC history. The problem is roster depth — there are simply not enough elite women who compete at 145 pounds to sustain a healthy division with regular activity.
Cris Cyborg was the UFC featherweight champion from 2017 to 2018, and her reign at the weight is the most significant thing the division has ever produced. When Amanda Nunes stopped her in 51 seconds at UFC 232, the championship picture at featherweight essentially collapsed. The division has been functionally inactive in the UFC since.
Featherweight is where Cris Cyborg lived and made everyone else look small. The division exists on paper and in history more than it does on current UFC cards. If it ever gets properly revived, it will be one of the most interesting weight classes in the sport.
