#2. Rose Namajunas - 2.5M followers
Rose Namajunas is yet to show us that she is the biggest female UFC star, especially since her last fight. Instead of defending her title and getting revenge on her old foe Carla Esparza, she surprisingly dropped the title in a truly bizarre fight. Despite that, she remains an incredibly popular fighter.

She has been a big name for the majority of her career, having first fought for the strawweight title back in 2014. While she was unsuccessful on that occasion, she became a massive star when she ended Joanna Jedrzejczyk's historic title reign with a shocking TKO.
Namajunas has since lost the belt, won it back and then lost it again in her most recent bout. While she would likely prefer not to have these ups and downs, fans have still invested heavily in her career. She's always in big-time fights and, at just 29 years of age, could still become a megastar in the sport.
#1. Valentina Shevchenko - 2.6M followers
Valentina Shevchenko is the number one pound-for-pound female fighter in the UFC and as such it should come as no surprise that she topped this list. Whilst Taila Santos came close, she ultimately became just another woman who has tried and failed to end Shevchenko's lengthy reign atop the division.
Shevchenko has been the champion since 2018 and now has seven successful title defenses. This dominance is incredibly rare in the sport of MMA and has understandably led to Shevchenko becoming a huge star internationally. She also speaks multiple languages, meaning she appeals to fans all over the world.
With her most recent opponent likely set for a lengthy spell of inactivity, it will be interesting to see who Shevchenko faces next. As mentioned previously, should Miesha Tate win in her upcoming fight, she could well earn the next title shot. A fight against another big name like Tate could further boost Shevchenko's popularity.
